Abstract :
A 540-kW continuous-wave (cw) klystron operating at 476 MHz was developed for use as a power source for testing PEP-II RF accelerating cavities and RF windows. It also serves as a prototype for a 1.2 MW cw klystron presently being developed as a potential RF source for asymmetric colliding ring use. The design incorporates the concepts and many of the parts used in the original 353 MHz PEP klystron developed sixteen years ago. The superior computer simulation codes available today result in improved performance with the cavity frequencies, drift lengths, and output circuit optimized for the higher frequency. The design and operating results of this tube are described with particular emphasis on the factors which affect efficiency and stability
