SPEAR 3 Upgrade Project: A Status Report
- SLAC
The SPEAR 3 upgrade project at SSRL will replace the original FODO lattice with a 234-m, 18-cell DBA lattice with gradient dipoles. The new hardware draws heavily on PEP-II B-Factory technology: a copper vacuum chamber, IGBT power supply technology, and mode-damped rf cavities to reach beam currents up to 500 mA at 3 GeV. First article magnets, supports, girders, vacuum chambers, pumps and RF components have been fabricated and a prototype girder assembly is nearing completion. I&C systems, radiation shielding and utility upgrades are in progress. In this paper we report on the status of the main accelerator subsystems.
