The MIT-Bates South Hall Ring

The MIT-Bates Linear Accelerator Center is in the process of constructing an electron storage ring. The 190-m ring will be used for internal target experiments with stored beams. It will also be used as a pulse stretcher to provide external beams with high duty factors. The present design incorporates a low beta region with a beta /sub x/ of 1 m and a 4.5 m-space between ring quadrupoles at the internal target location. The ring will contain up to 80 mA using two turn injection. Extraction using a one-half integer resonance will produce up to 50 mu A with a duty factor over 80%. Injection will occur at 1 kHz. Design extracted beam properties include an energy spread of 0.04% and an emittance as low as 0.01 pi mm-mr.<
