the CDMS-experiment has multiple different detector technologies in use, in particular, 2 types of detectors based on germanium or silicon, respectively, the experiments derived from some specific configuration of the CDMS-experiment detectors and different data-sets thus collected are sometimes given names like CDMS Ge, CDMS Si, CDMS II Si et cetera. Results On December 17, 2009, the collaboration announced the possible detection of two candidate WIMPs, one on August 8, 2007, and the other on October 27, 2007. Due to the low number of events, the team could exclude false positives from background noise such as neutron collisions. It is estimated that such noise would produce two or more events 25% of the time. Polythene absorbers were fitted to reduce any neutron background. A 2011 analysis with lower energy thresholds, looked for evidence for low-mass WIMPs (M < 9 GeV). Their limits rule out hints claimed by a new germanium experiment called CoGeNT and the long-standing DAMA/NaI, DAMA/LIBRA annual modulation result. Further analysis of data in Physical Review Letters May 2013, revealed 3 WIMP detections with an expected background of 0.7, with masses expected from WIMPs, including neutralinos. There is a 0.19% chance that these are anomalous background noise, giving the result a 99.8% (3 sigmas) confidence level. Whilst not conclusive evidence for WIMPs this provides strong weight to the theories. This signal was observed by the CDMS II-experiment and it is called the CDMS Si-signal (sometimes the experiment is also called CDMS Si) because it was observed by the silicon detectors. SuperCDMS search results from October 2012 to June 2013 were published in June 2014, finding 11 events in the signal region for WIMP mass less than 30 GeV, and set an upper limit for spin-independent cross section disfavoring a recent CoGeNT low mass signal. SuperCDMS SNOLAB A second generation of SuperCDMS is planned for SNOLAB. This is expanded from SuperCDMS Soudan in every way: The individual detector discs are 100 mm/3.9″ diameter × 33.3 mm/1.3″ thick, 225% the volume of the 76.2 mm/3″ diameter × 25.4 mm/1″ thick discs in Soudan. There are more of them, with room for 31 "towers" of six discs each, although operation will begin with only four towers. The detector is better shielded, by both its deeper location in SNOLAB, and greater attention to radiopurity in construction. The increase in detector mass is not quite as large, because about 25% of the detectors
