INSTALLATION AND OPERATION OF NEW KLYSTRON POWER SUPPLY WITH FAST SOLID-STATE SWITCH FOR KLYSTRON PROTECTION AT THE PHOTON FACTORY STORAGE RING

In the 2.5-GeV Photon Factory (PF) storage ring at KEK, one of the klystron power supplies was upgraded during a summer shutdown in 2003. The new power supply can provide a DC high voltage of up to 45 kV with the maximum current of 9 A. To protect the klystron under sparks, a noble solid-state switch was incorporated. This paper describes the design and the performance of the new power supply.
