Abstract

SSRL is planning to upgrade the 3 GeV SPEAR storage ring in FY 2002 to reduce the emittance from 160 nm-rad to 18 nm-rad and to increase the beam current from 100 to 200 mA, and then towards 500 mA as photon beam lines are upgraded. The core of the `SPEAR 3´ project includes new magnets and power supplies for a DBA lattice, vacuum chamber, and a mode-damped RF cavity system. Beam lines will see one to two orders of magnitude increase in performance and future high brightness insertion device beam lines are planned. The ring conversion will take place in a 6-month shutdown period to minimize the impact on the SSRL user program. SPEAR 3 lattice, beam properties, and accelerator system components are reviewed
