SSRL - National Scientific User Facility

The state-of-the-art SPEAR3 storage ring is operated at 3 GeV, with 9.6 nm-rad emittance and top-off injection at a current of 500 mA with a reliability of over 97%. The extremely bright x-rays are used by scientists and industrial researchers to conduct world-class research.

Planned SLAC Power Outage
