October saw the completion of our first experiment with pure 132Sn beams at energies above the Coulomb barrier. Sub-barrier fusion cross-section measurements have been taken using doubly stripped 132Sn beams from 453-560 MeV. Beam intensity averaged 20,000 ions/sec (i/s) and peaked at 30,000 i/s. With a new target-ion source this record was eclipsed in December and January when 100,000 i/s were achieved and for two 10-hour periods, 120,000-140,000 i/s were reached. In these later measurements, the beam energy was 475-495 MeV and used for a Coulomb excitation measurement.
More work is needed to understand all the factors involved in this exciting development. The later measurement used a new uranium-carbide target material manufactured at ORNL and used hydrogen-sulfide gas to chemically select Sn isotopes. The primary beam was approximately 10 uA of 42-MeV protons. In addition, a different beam tune through the second-stage mass separator was used which is applicable to beams with poor emittance and beams which do not require the high mass resolution of the the second-stage separator.
More details and reports on the experiments should be available in the next newsletter.

The last six months has been a remarkably productive period at HRIBF. During the last quarter of FY02, the HRIBF produced about 780 hours of beam on target for research, including 340 hours of radioactive fluorine beam. Following this successful fluorine campaign, which included such highlights as the first use of the DRS with radioactive ion beams, a campaign of neutron-rich RIB experiments was initiated. This campaign is still underway. During the first quarter of FY03, we recorded 1149 hours of beam on target for research, including 396 hours of radioactive beam. Since the end of December, we have added about 50 hours so that for the last six months we have logged in excess of 1900 research hours with almost 800 hours of this being radioactive beam. Experiments during the neutron-rich campaign have concentrated primarily on taking advantage of our pure tin capability. Highlights include the remarkable achievement of a measurement of the 132Sn + 64Ni evaporation residue excitation function extending to subbarrier energies and Coulex measurements on 128,130Sn. An effort to measure the B(E2) to the 4.04 MeV first excited state in 132Sn using the 150-crystal ORNL-MSU-TAMU BaF2 array is now in progress. During the course of this campaign, double-stripped 132Sn beams with a purity in excess of 99% have been produced with an intensity in excess of 140,000 ions per second on target. The corresponding single-stripped beam intensity should be greater than 600,000 ions per second on target. This is well over an order of magnitude improvement beyond the intensities we were advertising six months ago.
We hope to extend the present neutron-rich campaign until around mid-February. At that time, we will shut down for a major maintenance period of about ten weeks, which will involve substantial work on the tandem, including installation of a new and much improved gas stripper. Following the shutdown, a period of several weeks of stable beam running is planned, primarily for outside user experiments and equipment development and testing. In midsummer, we will initiate our next radioactive beam campaign. These plans are somewhat tentative because of considerable budget uncertainty and the constraints of the Continuing Resolution that we are now operating under. It is possible that the current campaign will have to be terminated early and the shutdown extended due to these budgetary constraints.
In the last issue of the newsletter, a brief discussion of the DOE Operations Review of the HRIBF in June of 2002 was provided. This review was quite favorable in most respects and recommended a substantial immediate increase in HRIBF funding to allow us to provide more hours of radioactive beam. It was also partially responsible for a modest reorganization of HRIBF management and the appointment of a new advisory committee. Alan Tatum has been appointed to the newly created position of Group Leader for RIB Production Systems, supported by Ray Juras who continues to be responsible for day-to-day operation of the HRIBF and ORELA. Darryl Dowling is now responsible for accelerator systems development and Dan Stracener is responsible for ISOL systems development. Cyrus Baktash continues as Group Leader for Experimental Systems. In this role he is responsible for the development of research equipment at the HRIBF and oversees the work of research support technical staff and equipment mentors. Jim Beene continues as HRIBF Director, Witek Nazarewicz as Scientific Director, and Carl Gross as User Liaison.
The report of the DOE Operating Review Panel also resulted in the formation of a new advisory panel to the HRIBF Director, the Scientific Policy Committee (SPC). The first meeting of the SPC was held November 22-23, 2002. The members include Chairman Juha Aysto (University of Jyvaskyla, Finland), Bradley W. Filippone (California Institute of Technology), Thomas Glasmacher (Michigan State University), John Hardy (Texas A&M University), Karl E. Rehm (Argonne National Laboratory), Alan Shotter (TRIUMF, Canada), Friedrich-Karl Thielemann (Institut fur Physik, Basel, Switzerland). This panel will provide advice on both technical and scientific directions of the facility.
The presentations to the Operating Review Panel covered a broad range of topics including the scientific program; results from recent experiments and the planned program of future running; possible new scientific programs to pursue; the means we use to solicit and obtain user community input to decisions about development investments in new beams and detectors; status of detectors and endstations and plans for upgrades to existing devices and addition of new devices to the HRIBF; status of various beam development projects; operations costs as well as recent and planned improvements to achieve more efficient operation; resources needed to increase current operation to over 2000 hours of RIB per year; and a proposed suite of upgrades to the facility and its detectors to enable reaching as much as 4000 hours of RIB per year out of a total of 6000 hours total operation. The report from the Panel recommended targeted increases in funding to provide more RIB hours immediately, as noted above, and also recommended a specific plan be developed for capital improvements to both accelerators and detectors which could be achieved over the next 5 years. Input from the User Community, particularly on the scientific direction and resulting implications for capital and development investment, is vital to the formation of this plan. Overall guidance will also be sought from the SPC noted above. We encourage Users to make their views known via usual liaison channels and also to the management and SPC members listed above. While Proposals and Letters of Intent to the HRIBF PAC remain a favored method for formal input on specific physics topics, many issues facing HRIBF as it evolves are of a strategic nature and will benefit from broad community input.

In the Summer 2001 newsletter, we reported the first results using neutron-rich radioactive ion beams (RIBs) from the HRIBF facility, including Coulomb excitation measurements of B(E2; 0+ --> 2+) in 126,128Sn and 132,134,136Te. The Te results have since been published [Radford et al., PRL 88,222501 (2002)]. Here we report on new experiments performed with neutron-rich RIBS during the Fall 2002.
The first experiments with isobarically pure tin radioactive beams were performed in the fall of last year, when we used Coulomb excitation to measure B(E2) values for 128,130Sn. Pure beams of 128,130Sn, with energies of 3 MeV per nucleon, were used to bombard a natural carbon foil at the target position of the Recoil Mass Spectrometer (RMS). Energetic carbon nuclei from target-beam collisions were detected at laboratory angles between 7 and 44 degrees in the HyBall. Gamma rays, detected by the segmented clover Ge detectors of CLARION, were recorded along with the HyBall data whenever they were in coincidence. Maximum beam intensities were about 3 x 106 s-1 (128Sn) or 5 x 105 s-1 (130Sn).
The purified beams were formed from molecular SnS+ ions from the target-ion-source. After selecting ions with the correct molecular weight, the sulfur is removed in a cesium vapor charge-exchange canal, and Sn- ions are mass analyzed in a second magnet for injection into the tandem accelerator. The Sn ions were primarily in their 0+ ground states, but 8.5% and 11% were in the metastable 7- state for 128Sn and 130Sn, respectively. Isobars of other elements made up less than 1% of these beams.
Spectra of gamma rays from 126,128Sn, gated by prompt coincidence with carbon recoils and Doppler-shift corrected, are shown in Figure 2-1. They are remarkably clean, due to the selectivity of the HyBall gate in discriminating against room background and decay of stopped beam particles. Also shown in this figure is a corresponding spectrum from an earlier experiment on 128Sn performed before the pure Sn beams were developed; the 128Sn made up about 14% of this A=128 beam.
Preliminary values for the B(E2; 0+ --> 2+) in Sn isotopes are listed in Table 1. They are also displayed together with the B(E2) systematics for this mass region in Figure 2-2. The quoted errors include contributions for systematic uncertainties in gamma-ray efficiencies, etc.
|B(E2; 0+ --> 2+) (e2b2)
The B(E2) value for 130Sn is remarkably small, corresponding to only 1.2 single-particle units. Due to the high excitation energy and low B(E2) for the 2+ level in this nucleus, the cross section for excitation of the level is only 1 millibarn. Clearly, without the isobarically pure beams, this measurement would have been extremely difficult.

Realistic nuclear structure problems are difficult to solve due to the complexity of the nucleon-nucleon interaction and the sheer sizes of the model spaces. In recent years, several approximations have been developed that truncate the model space while obtaining highly accurate approximations to low-lying states. Most truncation schemes are based on physical insights or random searches but do not really yield the optimal truncations. Exceptions are the density matrix renormalization group and the factorization method (See Ref. 1 for details) which we will describe here.
Let us expand the shell-model ground-state in terms of products of proton (p) and neutron (n) states as
Note that the norms decrease exponentially fast. This suggest that the factorization converges exponentially in the number K of retained states. Note that this exponential decay has also been observed in other systems ranging from spin-chains to lattice models in condensed matter to molecules in quantum chemistry. While the origin of this behavior is not well understood, it seems to be an empirical fact for many systems of physical interest.
We want to determine the optimal proton and neutron states for fixed number K of retained factors. The optimal factors are obtained from a variation of the energy and are the solution of a coupled eigenvalue problem:
As an example we computed the ground-state and low-lying excitations for the sd-shell nucleus 24Mg. Figure 3-2 shows the energy spectrum versus the dimension of the eigenvalue problem (relative to the dimension of the full m-scheme diagonalization, which is 28503). The energies converge exponentially quickly as the number of retained factors is increased. A good approximation to the exact spectrum (dashed lines) results already from the solution of an eigenvalue problem that has 30% of the full m-scheme dimension. We also studied pf-shell nuclei. For 48Cr, our method yields the ground-state energy within 100 keV by solving an eigenvalue problem with a dimension of only 8% compared to the full m-scheme diagonalization. This constitutes a reduction of the dimensionality by more than an order of magnitude and clearly demonstates the capability of the factorization method.
These first results are very encouraging, and we are currently examining the spin- and isospin structure of the computed ground states and low-lying excitations. Note that the exponential convergence of the factorization is at the heart of another numerical method, the density matrix renormalization group (DMRG). ORNL's nuclear theory group is presently developing this method to solve nuclear structure problems and has applied DMRG to compute critical exponents of spin-chains. The DMRG has the potential to explore exponentially large Hilbert spaces without ever letting the problem size getting out of hand. Its implementation to nuclear structure problems is, however, more cumbersome than the factorization method and also has led to some problems which are not yet fully understood. These truncation methods are rather new numerical tools. Related efforts of the nuclear theory group are the application of coupled cluster theory to nuclear structure and the delay of the minus sign problem in shell-model Monte Carlo methods.

The members of PAC-8 met in Oak Ridge on November 21-22, 2002. Sixteen proposals and letters of intent requesting 122 shifts of RIBs, 66 shifts of SIBs for RIBs, and 28 shifts of SIBs were considered. Of these, 11 received some allocation of beam time and 3 were deferred for more information and discretionary time. The titles and spokespersons may be viewed on our website. A total of 168 shifts (114 RIB, 44 SIB for RIB, and 10 SIB) were accepted requesting beams of radioactive Be, F, Ga, Ge, and Te. Notice that a new beam category has been added: SIB for RIBs. This category is for those experiments which use SIBs in preparation for RIBs - i.e., RIB-intensity SIBs to explore reactions and techniques which will be used for future RIB experiments.
We expect to issue the next Call for Proposals in May with PAC-9 tentatively scheduled for August 21-22. A new member, Alan Shotter from TRIUMF, will replace I-Yang Lee. We thank I-Yang for his service to the HRIBF.

Recent tests of new target materials have resulted in the measurement of two new proton-rich beams at the On-Line Test Facility (OLTF), namely, 34Cl and 27Si. In addition, a Cs-sputter type ion source has been modified and is now ready for its first tests with 7Be/Cu cathodes at the OLTF. Pure beams of Sn isotopes (including 132Sn) and Ge isotopes have been delivered to experiments. A surface-ionization ion source for positive ions is being modified and tested at the Ion Source Test Facility (ISTF1) and is almost ready for on-line tests. Another ion source development project was recently started to couple a He-jet target to a modified electron-beam-plasma (EBP) ion source. This system will be used to ionize fission fragments that are produced via photofission using 150-MeV electrons from the Oak Ridge Electron Linear Accelerator (ORELA) facility. The following paragraphs will provide more details of these projects.
Using an EBP ion source, we have measured beam intensities of 34Cl (half-life is 32.2 min) that were produced in a CeS target material using both (p,n) and (d,2n) reactions on 34S. The extracted radioactive beam intensities were in the range of 104 ions per second per microampere of production beam current with a target temperature of about 1900° C. The CeS target material (described in the previous Newsletter) showed no damage when inspected after the tests. The CeS was made from natural abundance material so the intensity of the 34Cl beam can be easily increased by a factor of twenty if the CeS targets were made from sulfur enriched in 34S. The 34Cl atoms were observed both as singly-charged positive ions and also as molecular ions such as AlCl+, which is similar to the fluorine case. The aluminum vapor concentration in the target was quite low during the measurement, but the yield of the aluminum chloride ions was slightly higher than the yield of the chlorine ions. This leads us to believe that the beam intensity of the molecular ions can be significantly increased if more aluminum atoms are added to the system. We plan to accomplish this by adding a sheath of aluminum oxide fiber around the target since this has worked well in the fluorine production target. Using molecules to transport the radioactive chlorine atoms should significantly shorten the effusion time and allow us to observe the much shorter lived 33Cl (half-life is 2.5 s) that is produced in a (d,n) reaction on 32S. Once we have maximized production and transport of chlorine atoms, we will couple this target to a negative ion source similar to the source used for the fluorine beam production.
Recent tests with an aluminum oxide fiber target have resulted in radioactive beams of 27Si (half-life is 4.14 s) from the (p,n) reaction on 27Al. The measured beam intensities in the initial tests are quite low (about 2000 ions per second per microampere of production beam) but there are several ideas for ways to increase the yield. As in the previous case, most of the observed activity was found in a molecular-ion channel, specifically, silicon sulfide. This is not too surprising since Si is in the same chemical family as Ge and Sn, which can be extracted from this EBP ion source as sulfide molecular ions with high efficiencies. In this test, the sulfur vapor concentration was very low, so we hope to increase the yields by increasing the amount of sulfur in the target. The target was operated at temperatures up to 1750° C and the target material showed no damage when inspected after the on-line tests. The target temperature can be increased to at least 1900° C if a hafnium oxide sheath is placed between the tantalum target holder and the aluminum oxide, and this should decrease the diffusion and effusion time which will reduce the losses due to radioactive decay during transport from the target to the ion source.
Recent efforts by the astrophysics group have resulted in the availability of 7Be atoms (half-life is 53.3 d) in the form of cathodes that can be used in a Cs-sputter type ion source. The 7Be was produced at the TUNL facility on the Duke University campus using 8-MeV protons from their FN tandem to irradiate a lithium pellet. About 30 mCi of 7Be was delivered to ORNL where the beryllium was separated from the lithium using wet chemical techniques in a hood at the ORELA facility. The 7Be activity was mixed with copper powder and pressed into aluminum holders that are designed to fit into a multi-sample target wheel to be used with a Cs-sputter ion source. Six such cathodes were made and are ready for testing. The ion source is also ready for testing, and the initial tests will be conducted in January 2003 at the OLTF. The ion source was developed and optimized at the ISTF1 and then modified slightly to fit onto the front end of the separator at the OLTF, which is identical to the front end of the RIB production platform. Once testing is completed, cathodes with about ten times the activity will be prepared for use on the RIB production platform.
Purified beams of Ge (~95%) and Sn (>99%) isotopes have been delivered to experiments using the technique where the isotope of interest is extracted as a sulfide molecular ion and then the negative ion is produced when the beam is passed through a Cs-vapor charge exchange cell. This process removes the isobaric contamination very efficiently allowing essentially pure beams to be delivered to experiments. The intensities and purities of the beams that were delivered are given in another article in this newsletter.
Development and testing of ion sources for production of radioactive ion beams is done at the ISTF1 and then on-line tests are made at the OLTF using low-intensity beams from the tandem electrostatic accelerator. A fairly simple positive surface-ionization source is being modified to fit in the standard ion source enclosure for the facility and will be ready for on-line tests at the OLTF in the near future. The ionization surface will be either a high-porosity carbon matrix with an iridium coating or a tubular surface of tantalum or tungsten depending on which design has the highest efficiency for Rb ions. The efficiency measurements for stable Rb ions and ion source emittance measurements are now being made at the ISTF1. This ion source will be coupled to a uranium carbide target to provide purified beams of neutron-rich isotopes of rubidium that are produced via proton-induced fission using 40-MeV protons.
All of the accelerated neutron-rich beams that are presently available at the HRIBF are produced using low energy (40 MeV) protons to induce fission in a uranium carbide target. Another way to produce beams of these fission fragments is being investigated. This involves photofission in uranium foils using the 150-MeV electron beam from ORELA. Calculations suggest that the production rates for some selected isotopes will be significantly higher using photofission than when using the low energy proton beam that is presently available. For example, the production rate of 82Ge in the target will increase by a factor of about 80 and the production rate of 132Sn will increase by about a factor of 800. The questions that must now be addressed are how efficiently can the fission fragments be transported to the ion source and what is the ionization efficiency.
The fission fragments will recoil out of the thin uranium foil, be stopped in a high pressure atmosphere of He gas that contains an aerosol, and then be transported to an ion source through a few meters of tubing. The aerosols, with the attached fission fragments, will be injected into the ion source with as little He gas as possible. The He will be removed using skimmers and side-jets but a significant flow rate (~0.03 liters/min) of He will still be injected into the ion source. Modifications to our standard EBP ion source have been made, and the measurements indicate that an unacceptable reduction in the efficiency of the ion source occurs at He flow rates that are greater than 0.02 liters/min, indicating that further development efforts are necessary. Continuing efforts will focus on development of the ion source to handle larger He flow rates and improved skimmer designs to more efficiently remove the He before it enters the ion source.

ORIC operated from the first week of August through the middle of September. In August a 3uA, 85-MeV alpha beam was used for 18F production. The only difficulty during this period occurred in late August when the electrostatic deflector began experiencing high drain current. The septum was found to have a small hole burned through it, and replacement of the septum corrected the problem with minimal downtime. In September, the experimental program shifted back to neutron-rich beam experiments, and ORIC provided 10uA of 42-MeV protons for this effort through the end of the calendar year. This was a very smooth operational period for ORIC, with the only major problem being a brief period of instability in the rf system tuning loop. In particular, ORIC operation resulted in 396 hours of RIB beam on target in the first quarter of FY03.
Regarding development, Tony Mendez has been exploring potential design changes to the ORIC ion source which have the potential to increase cathode lifetimes for helium operation. Several experiments are planned for the February-March time frame during the tandem accelerator tank opening. Additionally, new extraction system channels are being fabricated to assure a full complement of spares which incorporate small design changes made in recent months.
The Tandem Accelerator has operated for more than 2100 hours since the last report with almost 40% of the beam on target being RIB beams of 18F, 80Ge, 128Sn, 130Sn, 132Sn, and 132Te. The machine ran at terminal potentials of 2.33 to 23.73 MV and the stable beams 1H, 2H, 12C, 18O, 28Si, 32S, 48Ti, 58Ni, 80Se, 90Zr, 116Sn, 124Sn, 130Te, 138Ba, and 197Au, were also provided. The tandem ran for almost five months without opening for maintenance, when a lull in the schedule and excessive noise from the tank caused the machine to be opened. Two rotating shaft bearings were found to be failing and were replaced. Unfortunately, this was not the cause of the noise and a second tank opening was necessary. The noise was coming from a bearing on the column base chain sheave, but there was also a failure of the middle chain sheave bearing in the terminal. The column base bearing had been in service since being put in the tank more than twenty years ago and the terminal bearing had been replaced seventeen years ago. It is very lucky that we found the terminal bearing before complete failure since it could have caused a chain to break. About 170 hours were used to condition the machine for operation up to 24 MV. A good deal of the conditioning time was taken to correct problems in units 17 and 18 which had been causing ticking when the machine was above 22 MV.
During this reporting period, we delivered pure beams of
The 18F beams were produced via the 16O(4He,pn)18F reaction by bombarding a fibrous HfO2 target coupled to a Kinetic Ejection Negative Ion Source (KENIS) with 3 euA of 85-MeV 4He from the Oak Ridge Isochronous Cyclotron (ORIC). In the case of the pure 18F beam, the 18O contamination was eliminated by passing the beam from the 25-MV Tandem Electrostatic Accelerator through a thin carbon foil and selecting the 9+ charge state. The KENIS failed due to a short between the cone, grid, and ground. This failure mode occurred in the previous two ion sources of this type.
The heavy neutron-rich beams were produced via proton induced fission of 238U by bombarding a uranium carbide coating on both a reticulated vitreous carbon matrix target and a graphitic foam target coupled to an Electron Beam Plasma (positive) Ion Source (EBPIS) with 10 uA of 42-MeV 1H. The pure tin beams were produced by passing a positive tin sulfide beam through the recirculating cesium jet charge exchange cell and selecting the negative tin beam resulting from molecular breakup. Fortunately, there are no contaminating beams of the sulfides of tin isobars. Sulfur is introduced into the uranium carbide target by flowing hydrogen sulfide gas through a dedicated variable leak valve into the EBPIS internal gas feed line. A special gas manifold was installed on the third floor to accommodate the very hazardous hydrogen sulfide.
This is the first time that this technique has been used to produce pure heavy neutron rich beams accelerated to a few A-MeV.

The annual Users Executive Committee Election was held this fall. We would like to welcome Jeff Blackmon and David Radford to this committee. They will serve for three years and will replace Peter Parker and Krzysztof Rykaczewski. We thank Peter and Krzysztof for their service to the HRIBF. The committee membership is:
|Ani Aprahamian
|Notre Dame University
|Jeff Blackmon
|Oak Ridge National Laboratory
|Paul Mantica (chair)
|Michigan State University
|David Radford
|Oak Ridge National Laboratory
|Demetrios Sarantites
|Washington University
|Ed Zganjar
|Louisiana State University
The new Chair of the Users Executive Committee has the following message for HRIBF users:
The annual HRIBF Users Group Meeting was held at the Fall DNP Meeting in East Lansing this year. More than 80 people attended a joint session of Users Groups from HRIBF, 88-Inch, ATLAS, MSU, GAMMASPHERE, and RIA. Our session was chaired by Ani Aprahamian and presentations on the facility and recent research were given by Carl Gross and Witek Nazarewicz, respectively. The next meeting will be held at October's DNP meeting in Tucson, AZ.
``The Users Executive Committee would like to continue to encourage strong interactions between the on-site ORNL staff and outside users through workshops on special topics. The goals of the workshops are to enhance the available capabilities and provide an outside voice on developmental direction at HRIBF. Last year, a very successful transfer reactions workshop was hosted by ORNL and organized by Jolie Cizewski and Ray Kozub. If you have interest in organizing a workshop this year, please contact one of the members of the Users Executive Committee.
The HRIBF and the Users Executive Committee will also be considering ways to enhance the presence of outside users on future RIB experiments. The fact that RIB experiments present a host of challenges that may discourage potential users must be addressed. I would appreciate receiving comments from users on ways to foster a more active user group.'' -- Paul Mantica, Chair, Users Executive Committee.

HRIBF welcomes suggestions for future radioactive beam development. Such suggestions may take the form of a Letter of Intent or an e-mail to the Liaison Officer at email@example.com. In any case, a brief description of the physics to be addressed with the proposed beam should be included. Of course, any ideas on specific target material, production rates, and/or the chemistry involved are also welcome but not necessary. In many cases, we should have some idea of the scope of the problems involved.
Beam suggestions should be within the relevant facility parameters/capabilities listed below.

Defenders Blog: Apartment Problems & Solutions
Apartment Dwellers can find help with problems
SAN ANTONIO - If there is one complaint we hear frequently in the Defenders Department at KSAT 12, it's apartment problems.
Lots of them.
The complaints we receive cover a broad range of issues: mold, bugs, rodents, lack of repair work, security deposits not returned, and problem neighbors.
While we've covered stories through the years on many of these issues, there is one place where you can find all kinds of helpful information on apartment problems.
It's the Texas Tenant Advisor.
Among the advice: late fees have to be written into your lease agreement, and you also have a "grace" period of at least one day before the late fee can be charged.
Additionally, when you move into a new apartment, the law reads the landlord must re-key your locks, and must also provide a keyless bolting device on the door, as well as a door viewer on each exterior door.
We've heard from renters who want out of a lease because a crime was committed in the apartment complex. According to the Texas Tenants Advisor, the landlord is not obligated to let you out of your lease due to crime.
If you move, you'll have to pay applicable penalties.
You can find Texas Tenant Advisor at www.texastenant.org.
But it is worth mentioning, the best advice isn't online… it's just good common sense. ALWAYS read your lease agreement before you sign it.

New documents detail the events leading up to the fatal crash involving an Albuquerque Police Department sergeant.
According to the documents, some APD procedures may have been violated when it comes to using emergency equipment.
It's been two weeks since Ashley Browder was killed in a crash with APD Sgt. Adam Casaus.
KOB-TV obtained the initial crash report taken at the scene on February 10, 2013.
The report says the vehicle Browder and her sister were in was traveling north on Eagle Ranch Road.
Casaus was traveling west on Paseo del Norte, he told BCSO he was looking for a possible drunk driver when he went through a red light at the intersection and collided with Browder's vehicle.
The report says Casaus was "operating in a Code 3 response (lights and siren activated).
However, BCSO's investigation following the initial report has found while Casaus had his emergency lights on, he did not have his siren on.
This may be a violation of protocol, according to APD procedural orders.
The procedures say an officer responding to a Code 3, "response with full emergency equipment in operation."
Casaus says he was trying to catch up to a possible drunk driver, but the sheriff's office says it hasn't found proof of that yet.
APD procedural orders say: "Officers responding Code 3 will advise radio dispatch 'Code 3' prior to starting to the call."
But according to APD's call log, the last call Casaus was on was at 9:50 p.m.
Nothing else was reported after that call. APD said the crash happened before Casaus could call in the possible drunk driver.
According to the procedural orders in the section pertaining to Code 3 response, "when it is known that human life is not in immediate danger, the first unit may respond Code 2."
Code 2 says: response using emergency red lights.
Siren may be used to clear traffic and negotiate intersections.
APD and BCSO declined to comment as the investigation is ongoing.
BCSO's investigation is expected to be complete in about three more weeks.

Stepping into Liz's Life
Posted: May 23, 2012|
Hey! I'm Liz, and I'm the new blogger for the Health and Beauty team! I love writing... Why else would I be here! So I am hoping I'll be able to write some great stuff for you, which I'm really excited about!
I am also a massive cat lover, I have my own beauty called Mitzeee adopted from the fantastic people at the RSPCA. I love to illustrate, enjoy web design and I'm an Xbox girl too! But health and beauty really is my passion.
I'm 20-years-old and am originally from Birmingham but I moved to Stafford in hopes of greener pastures. My partner, and my best friend from the age of 14 or so, moved here for University and always came to visit me back in Birmingham because I was too scared of trains to visit Stafford! But one day, I decided, forget this, I'm coming back with you! And I did!
I was a nervous wreck, but I managed it. His lease was soon up, I'd practically moved in with him by then and I'd fallen in love with Stafford so we got a place together and I've been living here ever since. Life has only been getting better. I soon realised your surroundings and the people you surround yourself with, really DO contribute to your mental and even physical health!
I found beauty to be a massive boost for me. When I was younger, I was the type who never got sick and I was also the type to say (aside from my black nail polish) I never wear make up! But I ended up getting diagnosed with M.E while I was still in secondary school and my health declined from there.
Before I knew it, I was popping into Superdrug to get my prescriptions after visiting the doctor, and began covering my arms in swatches from the store's testers while I was waiting. I loved the rainbow of colours, and soon realised it was a new art form for me! Where my health had made me feel so bad, the colours and the experimenting made me feel much better about myself!
I loved seeing what went together, what didn't, what worked for me, what didn't and from then on, I started buying make up every time I was there! Eventually, my friends on Twitter convinced me to blog about what I thought and since then, I've been blogging about products I've tried, my favourites and generally sharing my opinion with others in the hope that someone would benefit. More recently, I did a post in regards to my health affecting me, the thing that started my obsession, my time spent in Superdrug and how my make up purchases became my own little treat to cheer me up. My readers loved it.
I'm a bundle of medical fun. I have quite a lot of pre-existing medical conditions. I suffer from M.E, Fibromyalgia, IBS, Asthma, Eczema and HMS, just to name but a few! I'm not a text book so you may find a lot of 'personal experience' here.
Though, as messy as my handwriting can be and despite my keen medical interest, I am not a Doctor, so my advice written in this blog is what I have tried and what has worked for me and others, but remember what works for one person, may not work for another. Therefore I can not guarantee it will work for you and please don't substitute your GP's advice for this blog. If you intend on taking any advice, it may be worth consulting your GP first, especially if you are under 16 or pregnant.
In this blog I will be giving you some seasonal advice, point out some fabulous trends and help you feel good about yourself! I will also spread my knowledge and raise awareness of health issues along with a few tips from my personal experience.
Coming next... About M.E. As M.E is a topic very close to my heart, I will be writing a post to help shed some light on the condition in the near future!

How about that wrestling team? Have you heard?
New head coach Pat Santoro is leading his team to a standout season—19-1 in dual meets so far. Success is always welcome on the Lehigh wrestling mat, of course, but it's particularly sweet during this milestone season, Lehigh's 100th.
Lehigh's wrestling program has a storied history, and many are about you, our alumni. It's been a real pleasure to hear those stories retold during this landmark year. It makes me proud to be associated with Lehigh. Check out some of the highlights of those 100 years
Of course, that's not all we have going on these days. Preparations are well underway for this year's Reunion weekend, in May—and we hope you're planning to return, even if it's not your official Reunion year. We've got plenty of great programs in the works. (Did you know the
Kingston Trio will perform
at Lehigh for the first time in 50 years?)
And while we're always thrilled to have you come back to Lehigh, we have several programs on the slate in which we will pack up, hit the road, and bring Lehigh to you. The
Florida Swing
, in February, will give our Florida contingent a chance to engage with Lehigh faculty and with each other.
Young alumni
will get together in March for their next Down the Coast event, a day of service, in which Lehigh alumni work together for a local charity, and have a great time reconnecting with each other.
Also in March, the
Career Networking Receptions
will help you make the most of your Lehigh family connections and develop your professional network—a vital career-building strategy, whether you're looking for a job right now or not. The CNRs will take place in seven cities around the country, from San Francisco to Washington, D.C.
There's a lot going on! Check out our list of upcoming events, and put Lehigh on your calendar! I hope to see you soon.

East Rutherford's regional semifinal postponed
With freezing rain moving into the Greensboro area around 5 p.m. Thursday evening, the North Carolina Athletic Association (NCHSAA) decided to postpone the 2A Western Region semifinal contest between East Rutherford and North Rowan. The game will be played Friday night at 5:30 p.m. at UNC-Greensboro's Fleming Gymnasium.
The final decision was made before the start of the the night's first semifinal between Hunter Huss and Smokey Mountain.
"Shy of putting on blue uniforms when you're supposed to be wearing white and red, this is about the crazy thing that's ever happened to us," East Rutherford head coach Brad LeVine said referencing the uniform debacle at this season's Dorman Classic. "But it doesn't rain, sleet or snow unless God wants it to."
The NCHSAA made reservations for East Rutherford to stay in an area hotel Thursday night.
"Thank goodness we brought practice uniforms because that's what they're going to be wearing to bed," LeVine said.
If East Rutherford wins on Friday, it will play Saturday at 4 p.m.for the Western Region championship.
"There's not a thing we can do about it so we'll just have to show up and play," LeVine said.

LB Quincy Black has cloudy future with Bucs
FEB 21, 2013 5:13p ET
On Thursday, Bucs general manager Mark Dominik told the Tampa Bay Times that the future of the six-year linebacker, taken out of New Mexico in the third round — 68th overall — in the 2007 draft, is questionable after the player underwent nerve graft surgery at the end of January. Dominik said it won't be known if the procedure is successful for a number of months.
Black, 28, has had restricted movement in his left arm since a scary collision with San Diego Chargers running back Ryan Mathews in Tampa Bay's Week 10 victory at Raymond James Stadium. Black was immobilized and carted off the field, and he was placed on injured reserve two days later.
"Don't think we're ready to make any comment at this time," Black's agent, Harold Lewis, wrote in an e-mail to FOXSportsFlorida.com. "Probably need to meet with team first."
Black, a 6-foot-2, 240-pound Chicago native, has 283 tackles and 3.5 sacks for his career. He had a career-high 84 tackles in 2009.
Black is set to make $5.5 million in base pay this season.

Kashgar, once a key centre of the ancient silk road, visited by merchants and famed travellers such as Marco Polo, lies in the autonomous region of Xingjiang in North Western China. The fabled city sits as a giant oasis, 1240m above sea level on the eastern border of the Taklimakan desert.
The journey from Northern Pakistan to Xingjiang takes us through a multitude of different panoramas. At 4730m the Kunjerab pass forms a natural border between Pakistan and China and, in the winter months, becomes impossible to cross, blocked by the cold, harsh forces of nature. From here the road winds on through a vast, mountainous desert, capped with snow. There is little in the way of vegetation, but donkeys and double humped camels can be seen plodding aimlessly along the plains of this dry and arid land.
Xingjiang is home to many ethnic minorities, such as the Uigur, Tajik, Kazakh and Uzbehk peoples, and the Chinese, making it a culturally diverse region. The first city along the highway is Tashkurgan (3600m), a predominately Tajik town, where ruins of a 600 year old fort overlook green pastures that are surrounded by snow topped, desert mountains. In this wee town we have our first taste of Chinese cuisine and our first lesson. Back in the hotel we discover we've been ripped off, having paid triple the usual price for our meal. We learn that our foreign faces signify 'loads of cash'. Our lesson - always know and agree on the price before ordering and eating. The food was excellent by the way.
After travelling through Pakistan it was almost shocking to see women's bare arms and legs again. The first Tajik woman we saw wore a frilly white dress, stockings, red high heels, and a small head scarf, her face painted white like someone off an opera stage. Two months in Pakistan, where women covered themselves from head to toe, had taken their toll and I wondered how many brothels there were in town.
It was an incredible fight to get on the bus to Kashgar. There weren't enough seats for the amount of tickets that had been sold. People pushed and shoved to sit themselves down, there were no pleasantries. The bus was jammed with biscuits, kitchenware and fabrics from Pakistan and a wild array of people including Pakistanis, Chinese, Tajiks, Uigars, two Japanese, and us - a Brazilian and a New Zealander. Travelling eastwards we passed a few nomadic settlements, looking as if time had never touched them. Camels sat parked outside tents made of animal hide, while children ran about playing without any cares.
Soon the scenery became dominated by the 7540m Muztagh Aga (Father of Ice Mountains) and Mount Kongur (7720m). Lying in the laps of these mighty mountains is Lake Karakol creating spectacular desert scenery of water, sand and snow. At the lakeside the bus stopped for a lunch break, and although there is no town, there is tourist nomadic tent style accommodation, a couple of restaurants, souvenirs and the chance to have a picture taken with a two humped camel. We thought the scenery was worth an overnight stay, so we caught a bus onwards the next day.
From the lake, the road takes us through more desert scenery finally plunging down into the Ghez river canyon and onto the plains. Small towns and signs of agriculture begin to appear. We take a break, from the arse breaking bus ride, at a small town where horse and carts are still the main mode of transport. The atmosphere of this timeless place more like that of the old Soviet Union or Eastern Europe. The men wear shirts, trousers, blazers and caps, and women dress in knee length frocks, stockings, high heels and cover their hair with small, colourful scarves. Young boys play pool in an outdoor hall surrounded by noodle and bagel stalls. Not many tourists visit this town, and the towns people are most curious about our foreign faces. On the road again we finally arrive in Kashgar after 10 hours of a dusty, bumpy but incredibly scenic ride.
The majority of the 200,000 people that live in Kashgar are Uigur, though the population of Chinese is forever increasing. Uigur people are followers of the Islamic faith, their written script is Arabic, their language closely related to Turkish and their physical features more or less Caucasian. Although the Chinese have done a great deal to improve the living conditions in the region such as building roads, railways hospitals and industry, there is an air of tension between the Uigars and the Chinese. Understandably, the Uigars cannot forgive their compatriots for their past wrong-doings, such as once replacing all Arabic script taught in schools with Chinese characters, the closing of the mosques during the cultural revolution and the past centuries of misrule by the Chinese. Or maybe it simply comes down to present religious and cultural differences.
Id Kah mosque is the center of Uigur activity. Muslims pray at five set times during the day and Friday is Sabbath. Fridays are exceptionally busy at the mosque. Exotic faces from the past, come from the city and surrounding countryside, ambling into the mosque to find peace and prayer. It's a religious and social event. Uigur men arrive with long beards and dress in their finest fur coats and embroidered caps. Women, although not permitted into the interior of the mosque, are also around for the event. Some in long dark dresses, their heads and faces covered with large brown gauze scarves. Others take a less severe approach wearing knee length dresses, sequined material a favourite, stockings and small head scarves that cover only their hair.
Around the mosque a maze of narrow streets make up the market place. Kashgar is a hat making center, here milliners make and sell felt caps, embroidered Muslim caps and exotic fur lined hats made from sheep, goat and occasionally snow leopard or marmot skins. Knives are another specialty of the region and are especially ornate. On the roadside blacksmiths pound their anvils and coppersmiths beat out urns and pots. Shoe repair men work with simple tools and pieces of string. Old bearded men sell Muslim prayer beads and Koran's decorated with beautiful calligraphy. Everywhere you look there is a scene from another time.
First thing in the morning the aroma of freshly baked bagels lingers in the air, caressing the olfactory senses. This bread is definitely at its best while it's still warm, as it turns into a some kind of rock formation on cooling. But the food on the streets does not always tempt ones optical senses. Chicken feet and heads are a local delicacy along with the heads of goats and sheep. Savoury dishes of offal and intestine steam on street corners and are eaten with gusto. Apart from these fine foods, you can find delicious dumplings filled with meat or vegetables which are rolled and steamed in front of you, certifying their freshness. Outside restaurants, culinary experts swing their dough producing perfect noodles to make tasty chow miens and soups. The streets are filled with local culinary delights.
On Sundays the shopping focus shifts to the eastern outskirts of town. Traffic jams of horses and carts carrying produce and passengers, block the main road as people from the country side pour into town for the Sunday Market. It's a huge event. Live stock for sale includes horses, fat bottomed sheep, goats, cattle, yaks and camels. Amongst the animals men bargain and fight for the best market price, puffing on and offering cigarettes in the hope of a good deal.
In the fruit and vegetable market the choices are numerous. Sweet melons, grapes, oranges and apples. Choice tomatoes, cabbages, green vegetables, spring onions, garlic and ginger. In the fabric section sequined women bargain for the choicest cloths, the gaudier the better. In restaurants noodles and odd delicacies are munched on while watching loud c-grade movies, each establishment competing for noise space. The markets is alive with bargain hunters and merchants. It's a fascinating place to spend the day watching and wandering.
We went to Kashgar having no idea what we would find. What we found was a hospitable and almost timeless people, fighting to hold onto their culture. Though not as exotic as its silk route days, Kashgar retains a uniqueness in its ever changing motherland. Despite the white statue of Chairman Mao in the main street, the city stands a world apart from greater China as its minorities fight to hold onto their autonomy.
