Overview of the Superconducting Super Collider rf systems

The SSC will have a linear accelerator (Linac) and five synchrotron systems (three booster synchrotrons plus two main synchrotron rings which constitute the collider). The Linac consists of three major accelerating systems an rf Quadrupole (RFQ), a Drift Tube Linac (DTL) and a Side Coupled Cavity Linac (CCL), plus buncher and compressor systems. The various Linac structures will be driven by solid-state, tetrode, and klystron amplifiers at power levels that range from less than a 1 kW to 15 MW peak power. The three booster synchrotron rf systems will utilize a multiplicity of high power vhf 160 KW tetrode amplifiers, whereas the collider rf systems will utilize four 360-MHz, 1-MW cw klystrons. The rf systems include dc power supplies, local control and monitoring systems, and accelerating cavities, as well as the rf amplifiers. The system requirements and conceptual designs for the rf systems for the Linac and the five SSC synchrotrons are presented. The status of the Linac rf systems and the Low Energy Booster Synchrotron accelerating cavity and ferrite tuner development programs are specifically addressed. 5 figs., 3 tabs
