What is SNS?
• World’s highest power pulsed spallation neutron source• Consists of a 1 GeV superconducting linear accelerator,
accumulator ring, and a flowing liquid mercury target• Operates as a National User Facility for conducting
neutron scattering research– 13 instruments in User Program– 6 in commissioning or under construction
• Funded by the Department of Energy’s Office of Basic Energy Sciences (~$181M/year)
