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 hard x-ray energy region and 
a suite of beamlines optimized for this source.

(1) FLUX.—The term ‘‘flux’’ means the rate of 
flow of photons. 
(2) HARD
X-RAY.—The term ‘‘hard x-ray’’ 
means a photon with energy greater than 20 
kiloelectron volts.

UNDERGROUND NEUTRINO EXPERIMENT. 
(a) IN GENERAL.—The Secretary of Energy shall 
provide for a Long-Baseline Neutrino Facility to facilitate 
the international Deep Underground Neutrino Experiment 
to enable a program in neutrino physics to measure the 
fundamental properties of neutrinos, explore physics be-
yond the Standard Model, and better clarify the nature 
of matter and antimatter. 
(b) FACILITY CAPABILITIES.—The Secretary shall 
ensure that the facility described in subsection (a) will pro-
vide, at a minimum, the following capabilities: 
(1) A broad-band neutrino beam capable of 1.2 
megawatts (MW) of beam power and upgradable to 
2.4 MW of beam power. 
(2) Four caverns excavated for a forty kiloton 
fiducial detector mass and supporting surface build-
ings and utilities. 
(3) Neutrino detector facilities at both the Far 
Site in South Dakota and the Near Site in Illinois 
to categorize and study neutrinos on their 800-mile 
journey between the two sites. 
(4) Cryogenic systems to support neutrino de-
tectors. 
(c) START OF OPERATIONS.—The Secretary shall, to 
the maximum extent practicable, ensure that the start of
