RF cavity for the medium energy booster for SSCL

The RF cavity for the Medium Energy Booster (MEB) is required to accept beam from the low energy booster (LEB) at a momentum of 12 GeV/c (possibly 10 GeV/c) and accelerate it to 200 GeV/c. Each cavity must provide a maximum gap voltage of 250 kV, and must be tunable from 59.7 MHz to 59.96 MHz with a maximum sweep rate of 450 kHz/s. This requires a ferrite-tuned cavity with a high quality factor. A quarter-wave cavity was designed which meets these requirements while minimizing beam-loading problems (minimizes R/Q). This paper describes the design of this cavity, results from measurements of a corresponding cold model, and several proposed higher order mode damping system designs.<
