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)
