R. 4376 [Report No. 115–556] IN THE HOUSE OF REPRESENTATIVES November 13, 2017 Mr. Knight (for himself, Mr. Lipinski , Mr. Smith of Texas , Mr. Weber of Texas , and Mr. Hultgren ) introduced the following bill; which was referred to the Committee on Science, Space, and Technology February 13, 2018 Committed to the Committee of the Whole House on the State of the Union and ordered to be printed A BILL To direct the Secretary of Energy to carry out certain upgrades to research equipment and the construction of a research user facility, and for other purposes.

1. Short title This Act may be cited as the Department of Energy Research Infrastructure Act of 2017 . 2. Advanced Light Source upgrade (a) In general The Secretary of Energy shall provide for the upgrade to the Advanced Light 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 soft x-ray energy region. (b) Definitions In this section: (1) Flux The term flux means the rate of flow of photons. (2) Soft x-ray The term soft x-ray means a photon with energy in the range from 50 to 2,000 electron 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 section occurs before December 31, 2026. (d) Funding Out of funds appropriated to the Office of Science, there shall be made available to the Secretary to carry out the upgrade under this section— (1) $20,000,000 for fiscal year 2018; (2) $50,000,000 for fiscal year 2019; (3) $80,000,000 for fiscal year 2020; (4) $80,000,000 for fiscal year 2021; (5) $52,000,000 for fiscal year 2022; (6) $22,000,000 for fiscal year 2023; and (7) $6,000,000 for fiscal year 2024. 3. Linac Coherent Light Source II high energy upgrade (a) In general The Secretary of Energy shall provide for the upgrade to the Linac Coherent Light Source II facility 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 experimental capabilities for high energy x-rays to reveal fundamental scientific discoveries. The Secretary shall ensure the upgrade under this section enables the production and use of high energy, ultra-short pulse x-rays delivered at a high repetition rate. (b) Definitions In this section: (1) High energy x-ray The term a high energy x-ray means a photon with an energy at or exceeding 12 kiloelectron volts. (2) High repetition rate The term high repetition rate means the delivery of x-ray pulses up to one million pulses per second. (3) Ultra-short pulse x-rays The term ultra-short pulse x-rays means x-ray bursts capable of durations of less than one hundred femtoseconds. (c) Start of operations The Secretary shall, to the maximum extent practicable, ensure that the start of full operations of the upgrade under this section occurs before December 31, 2025. (d) Funding Out of funds appropriated to the Office of Science, there shall be made available to the Secretary to carry out the upgrade under this section— (1) $20,000,000 for fiscal year 2018; (2) $55,000,000 for fiscal year 2019; (3) $80,000,000 for fiscal year 2020; (4) $80,000,000 for fiscal year 2021; (5) $54,000,000 for fiscal year 2022; and (6) $31,000,000 for fiscal year 2023. 4. Facility for Rare Isotope Beams (a) In general The Secretary of Energy shall provide for a Facility for Rare Isotope Beams to advance the understanding of rare nuclear isotopes and the evolution of the cosmos. (b) Facility capability In carrying out subsection (a), the Secretary shall provide for, at a minimum, a rare isotope beam facility capable of 400 kW of beam power. (c) Start of operations The Secretary shall, to the maximum extent practicable, ensure that the start of full operations of the facility under this section occurs before June 30, 2022, with early operation in 2018. (d) Funding Out of funds appropriated to the Office of Science, there shall be made available to the Secretary to carry out activities, including construction of the facility, under this section— (1) $101,000,000 for fiscal year 2018; (2) $103,000,000 for fiscal year 2019; (3) $104,000,000 for fiscal year 2020; (4) $105,000,000 for fiscal year 2021; and (5) $106,000,000 for fiscal year 2022.
