Be it enacted by the Senate and House of Representa-
tives of the United States of America in Congress assembled, 
SECTION 1. SHORT TITLE. 
This Act may be cited as the ‘‘Department of Energy 
Research Infrastructure Act of 2017’’. 
SEC. 2. ADVANCED LIGHT SOURCE UPGRADE. 
(a) IN GENERAL.—The Secretary of Energy shall 
provide for the upgrade to the Advanced Light Source de-
scribed in the publication approved by the Basic Energy 
Sciences Advisory Committee on June 9, 2016, titled ‘‘Re-
port 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 Of-
fice of Science, there shall be made available to the Sec-
retary 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. 
SEC. 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 en-
ergy 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 capa-
ble 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.
