As part of the activities authorized under section 7139 of this title, the Director shall carry out a research program in elementary particle physics and advanced technology research and development to improve the understanding of the fundamental properties of the universe, including constituents of matter and energy and the nature of space and time.
As part of the program described in subsection (b), the Director shall carry out research using high energy accelerators and advanced detectors, including accelerators and detectors that will function as national user facilities, to create and study interactions of elementary particles and investigate fundamental forces.
The Director shall carry out research activities on rare decay processes and the nature of the neutrino, which may include collaborations with the National Science Foundation or international collaborations.
The Secretary shall support construction of a Long-Baseline Neutrino Facility to facilitate the international Deep Underground Neutrino Experiment to examine the fundamental properties of neutrinos, explore physics beyond the Standard Model, and better clarify the existence and nature of antimatter.
The Secretary shall, subject to the availability of appropriations, ensure that the start of full operations of the facility described in subparagraph (A) occurs before December 31, 2031.
The Secretary shall support construction of the Proton Improvement Plan II, an upgrade to the Fermilab accelerator complex identified in the 2014 Particle Physics Project Prioritization Panel (P5) report entitled “Building for Discovery”, to provide the world’s most intense beam of neutrinos to the international Long Baseline Neutrino Facility and to carry out a broad range of future high energy physics experiments. The Secretary shall work with international partners to enable further significant contributions to the capabilities of that project.
The Secretary shall, subject to the availability of appropriations, ensure that the start of full operations of the facility described in subparagraph (A) occurs before December 31, 2028.
The Secretary, in partnership with the Director of the National Science Foundation, shall support construction of the Cosmic Microwave Background Stage 4 project to survey the cosmic microwave background to test theories of cosmic inflation as described in the 2014 Particle Physics Prioritization Panel (P5) report entitled “Building for Discovery: Strategic Plan for U.S. Particle Physics in the Global Context.”.[1]
The Secretary shall consult with the private sector, institutions of higher education, National Laboratories, and relevant Federal agencies to ensure that the project described in subparagraph (A) is capable of meeting Federal research needs in accessing the ultra-high energy physics of inflation and important neutrino properties.
The Secretary shall ensure to the maximum extent practicable that the facility described in subparagraph (A) will provide, at a minimum, 500,000 superconducting detectors deployed on an array of millimeter-wave telescopes with the required range in frequency, sensitivity, and survey speed that will provide sufficient capability to enable an order of magnitude advance in observations of the Cosmic Microwave Background, delivering transformative discoveries in fundamental physics, cosmology, and astrophysics.
The Secretary shall, subject to the availability of appropriations, ensure that the start of full operations of the facility described in subparagraph (A) occurs before December 31, 2030.
The Director shall upgrade accelerator facilities and detectors, as necessary and appropriate, to increase beam power, sustain high reliability, and improve precision measurement to advance the highest priority particle physics research programs. In carrying out facility upgrades, the Director shall continue to work with international partners, when appropriate and in the United States’ interest, to leverage investments and expertise in critical technologies to help build and upgrade accelerator and detector facilities in the United States.
As part of the program described in subsection (b), the Director shall carry out research and development in particle beam physics, accelerator science and technology, and particle and radiation detection with relevance to the specific needs of the High Energy Physics program, in coordination with the Accelerator Research and Development program authorized under section 18648 of this title.
