priate, consistent with section 209 of the Depart-
ment of Energy Organization Act (42 U.S.C. 7139). 
(d) LIGHT SOURCE LEADERSHIP INITIATIVE.— 
(1) ESTABLISHMENT.—In support of the sub-
program authorized in subsection (c), the Director 
shall establish an initiative to sustain and advance 
global leadership of light source user facilities. 
(2) LEADERSHIP STRATEGY.—Not later than 9 
months after the date of enactment of this Act, and 
biennially thereafter, the Director shall prepare, in 
consultation with relevant stakeholders, and submit 
to the Committee on Science, Space, and Technology 
of the House of Representatives and the Committee 
on Energy and Natural Resources of the Senate a 
light source leadership strategy that— 
(A) identifies, prioritizes, and describes 
plans for the development, construction, and op-
eration of light sources over the next decade;

(B) describes plans for optimizing manage-
ment and use of existing light source facilities; 
and 
(C) assesses the international outlook for 
light source user facilities and describes plans 
for United States cooperation in such projects. 
(3) ADVISORY
COMMITTEE
FEEDBACK
AND 
RECOMMENDATIONS.—Not later than 45 days after 
submission of the strategy described in paragraph 
(2), the Basic Energy Sciences Advisory Committee 
shall provide the Director, the Committee on 
Science, Space, and Technology of the House of 
Representatives, and the Committee on Energy and 
Natural Resources of the Senate a report of the Ad-
visory Committee’s analyses, findings, and rec-
ommendations for improving the strategy, including 
a review of the most recent budget request for the 
initiative.
