Development of a thermionic magnicon amplifier at 11.4 GHz

摘要

Summary form only given. A new 11.4 GHz rep-rated thermionic magnicon experiment is being assembled, using an advanced ultrahigh-convergence electron gun driven by a 10 Hz, 1.5 microsecond modulator top to produce a 500 kV, 210 A, 2-mm diameter electron beam. The magnicon circuit has been optimized for minimum surface RF fields and maximum efficiency, and will be engineered for high temperature bakeout and high vacuum operation. This experiment should begin operation in the summer of 1997. The predicted power is 60 MW at /spl sim/60% efficiency.
