; (B) neutron sources; (C) nanoscale science research centers; and (D) such other facilities as the Director considers appropriate, consistent with section 209 of the Department of Energy Organization Act ( 42 U.S.C. 7139 ). (d) Basic energy sciences research infrastructure (1) Advanced photon source upgrade (A) In general The Secretary shall provide for the upgrade to the Advanced Photon Source described in the publication approved by the Basic Energy Sciences Advisory Committee on June 9, 2016, titled Report on Facility Upgrades , including the development of a multi-bend achromat lattice to produce a high flux of coherent x-rays within the hard x-ray energy region and a suite of beamlines optimized for this source. (B) Definitions In this paragraph: (i) Flux The term flux means the rate of flow of photons. (ii) Hard x-ray The term hard x-ray means a photon with energy greater than 20 kiloelectron volts. (C) Start of operations The Secretary shall, to the maximum extent practicable, ensure that the start of full operations of the upgrade under this paragraph occurs before December 31, 2025. (D) Funding Out of funds authorized to be appropriated under section 11 for Basic Energy Sciences, there shall be made available to the Secretary to carry out the upgrade under this paragraph— (i) $93,000,000 for fiscal year 2018; and (ii) $130,000,000 for fiscal year 2019. (2) Spallation neutron source proton power upgrade (A) In general The Secretary shall provide for a proton power upgrade to the Spallation Neutron Source. (B) Definition of proton power upgrade For the purposes of this paragraph, the term proton power upgrade means the Spallation Neutron Source power upgrade described in— (i) the publication of the Office of Science of the Department of Energy titled Facilities for the Future of Science: A Twenty-Year Outlook , published December 2003
