STARTUP OF RF SYSTEM FOR VEPP-5 BOOSTER RING

RF system for VEPP-5 booster ring has been created at Budker INP. It operates at 700 MHz and consists of the RF power source based on KU-393 klystron, waveguide section with wave-to-coax transitions, accelerating cavity, and control system. The cavity higher order modes are damped by resistive loads to eliminate the beam instability. Resul ts of the cavity cold tests and RF system high power level tests are presented.
