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 LANSCE accelerator is experiencing difficulties with one of the accelerating structures that requires repair. This repair will delay the startup of the 2019 run-cycle, originally planned for June 19. To maximize the available beam time, we will have a rolling start date for the different target stations. All dates given below are approximate and dependent upon the success of the repair effort.
June 21: Beam operations to the Isotope Production Facility
July 1: Beam operations to Proton Radiography and the Ultra-cold Neutron Facility
July 3: Beam operations to the Weapons Neutron Research Facility
July 18: Beam operations to the Lujan Center
