Neutron and Proton Science at LANSCE

Serving an international user community in support of civilian and national security research

LANSCE Capabilities

For more than 30 years the Los Alamos Neutron Science Center (LANSCE) has provided the scientific underpinnings in nuclear physics and material science needed to ensure the safety and surety of the nuclear stockpile into the future. In addition to national security research, the LANSCE User Facility has a vibrant research program in fundamental science, providing the scientific community with intense sources of neutrons and protons to perform experiments supporting civilian research and the production of medical and research isotopes.

The LANSCE User Program plays a key role in training the next generation of top scientists and in attracting the best graduate students, postdoctoral researchers, and early-career scientists. The U.S. Department of Energy (DOE), National Nuclear Security Administration (NNSA)—the principal sponsor of LANSCE—works with the Office of Science and the Office of Nuclear Energy, which have synergistic long-term needs for the linear accelerator and the neutron science that is the heart of LANSCE.

















The health and safety of our staff and users is of paramount importance to us. As the COVID-19 coronavirus spreads around New Mexico and the country, LANL has curtailed operations (see Director Thom Mason’s memo) and we at LANSCE have made the decision to postpone the beginning of the 2020 run cycle.
The approved start of the run cycle is September 4, 2020. The run cycle will end on Dec. 21, 2020. Please find a the detailed schedule here.
Since it is our desire to operate the user program as much as possible this year, we will proceed with the review of proposals using our Nuclear and Materials Program Advisory Committees. It is our intent to inform users on the status of proposals once these reviews are complete.
We are striving to develop COVID-19 compliant protocols to allow external users on site to conduct experiments at LANSCE. If approved, we will share the process with our users.
