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 for LANSCE. At this time LANSCE has paused all work not related to the production of medical isotopes. This means that the normal accelerator maintenance and startup activities required for 800-MeV operations and neutron production is paused. It is our intent to resume these activities as soon as the situation permits. This will lead to a delay in the start of the run cycle and at this time we cannot schedule a new start date for the run cycle.
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. These reviews will be conducted remotely. It is our intent to inform users on the status of proposals, however it won’t be possible to schedule proposals until we know the overall schedule for LANSCE operations. If you have detailed questions please contact your LANL point of contact. We ask for your patience and understanding during these difficult times.
