5 (a) IN GENERAL.—The Secretary of Energy shall 

6 provide for the upgrade to the Advanced Light Source de7 scribed in the publication approved by the Basic Energy 

8 Sciences Advisory Committee on June 9, 2016, titled ‘‘Re9 port on Facility Upgrades’’, including the development of 

10 a multi-bend achromat lattice to produce a high flux of 

11 coherent x-rays within the soft x-ray energy region. 

12 (b) DEFINITIONS.—In this section: 

13 (1) FLUX.—The term ‘‘flux’’ means the rate of 

14 flow of photons. 

15 (2) SOFT X-RAY.—The term ‘‘soft x-ray’’ means 

16 a photon with energy in the range from 50 to 2,000 

17 electron volts. 

18 (c) START OF OPERATIONS.—The Secretary shall, to 

19 the maximum extent practicable, ensure that the start of 

20 full operations of the upgrade under this section occurs 

21 before December 31, 2026. 

22 (d) FUNDING.—There are authorized to be appro23 priated to the Secretary for the Office of Science to carry 

24 out to completion the upgrade under this section— 

25 (1) $20,000,000 for fiscal year 2018; 

26 (2) $50,000,000 for fiscal year 2019;

5 (7) $6,000,000 for fiscal year 2024. 

6 SEC. 3. LINAC COHERENT LIGHT SOURCE II HIGH ENERGY 

7 UPGRADE. 

8 (a) IN GENERAL.—The Secretary of Energy shall 

9 provide for the upgrade to the Linac Coherent Light 

10 Source II facility described in the publication approved by 

11 the Basic Energy Sciences Advisory Committee on June 

12 9, 2016, titled ‘‘Report on Facility Upgrades’’, including 

13 the development of experimental capabilities for high en14 ergy x-rays to reveal fundamental scientific discoveries. 

15 The Secretary shall ensure the upgrade under this section 

16 enables the production and use of high energy, ultra-short 

17 pulse x-rays delivered at a high repetition rate. 

18 (b) DEFINITIONS.—In this section: 

19 (1) HIGH ENERGY X-RAY.—The term a ‘‘high 

20 energy x-ray’’ means a photon with an energy at or 

21 exceeding 12 kiloelectron volts. 

22 (2) HIGH REPETITION RATE.—The term ‘‘high 

23 repetition rate’’ means the delivery of x-ray pulses 

24 up to one million pulses per second.

1 (3) ULTRA-SHORT PULSE X-RAYS.—The term 

2 ‘‘ultra-short pulse x-rays’’ means x-ray bursts capa3 ble of durations of less than 100 femtoseconds. 

4 (c) START OF OPERATIONS.—The Secretary shall, to 

5 the maximum extent practicable, ensure that the start of 

6 full operations of the upgrade under this section occurs 

7 before December 31, 2025. 

8 (d) FUNDING.—There are authorized to be appro9 priated to the Secretary for the Office of Science to carry 

10 out to completion the upgrade under this section—
