Overview and status of RF systems for the SSC linac

The Superconducting Super Collider (SSC) linear accelerator (linac) produces a 600-MeV, 35-/spl mu/s, H/sup -/ beam at a 10-Hz repetition rate. The beam is accelerated by a series of RF cavities. These consist of a radio frequency quadrupole (RFQ), two bunchers, and four drift tube linac (DTL) tanks at 427.617 MHz, and two bunchers, nine side-coupled linac modules, and an energy compressor at 1282.851 MHz. The RFQ amplifier and the low-frequency buncher cavity amplifiers use gridded tubes, while the other cavities use klystron amplifier systems. The RF control system consists of a reference line and cavity feedback and feedforward loops for each amplifier. The RF amplifier system for each of these accelerator cavities is described, and the current status of each system is presented.<>
