PEP-II Asymmetric B Factory: Designs Update and R& D Results
- SLAC
PEP-II, a 9 GeV x 3.1 GeV e{sup +}e{sup -} collider with a design luminosity of 3 x 10{sup 33} cm{sup -2}s{sup -1}, was proposed jointly by SLAC, LBL, and LLNL. Recent efforts have continued towards an optimized design. In addition, an aggressive R&D program is under way to validate our design choices. Fabrication of a low-power prototype RF cavity is complete, and impedance measurements are beginning. A 500-kW, 476-MHz klystron has been completed; it will be used for testing both high-power RF windows and a prototype high-power cavity (now under design in collaboration with Chalk River Laboratory). Vacuum studies have demonstrated that chambers with suitable photodesorption properties can be fabricated. A mock-up of the two-ring arc area has been completed and used to investigate alignment and stability issues. The PEP-II project is ready to begin construction as soon as funds become available.
