Design of an accelerating cavity for the Superconducting Super Collider Low-Energy Booster

The authors present the history and status of the design of the accelerator cavity to be incorporated into the Low-Energy Booster (LEB) of the Superconducting Super Collider (SSC). The LEB is a proton synchrotron, 540 m in circumference, and having 108 buckets around the ring. Acceleration programs, each 50-ms long, take place at a rate of 10/s. The beta change of the particles from injection to extraction is from 0.8 to 0.997. Since the RF excitation frequency must track beta, the RF frequency must shift from 47.5 to 60 MHz over the 50-ms acceleration program. The cavity will use ferrite in a perpendicular control bias mode to effect the required tuning.<
