Three-cavity circuit studies of the Maryland gyroklystron

摘要

At the University of Maryland we have examined an X-Band TE(sub 01) mode three-cavity gyroklystron circuit that includes a tunable buncher cavity. The system parameters are: 425 kV, 100--200 A, pulse length (approximately) 1 (mu)s, operating frequency 9.85 GHz, and a beam alpha, (upsilon)(perpendicular)/(upsilon)(sub z), in the range 0.7--1.0. This circuit produced a maximum power of 27 MW at 32% efficiency and a gain of 36 dB. We will summarize the major results of the three-cavity systems, including recent output cavity configurations that were to affect the post-cavity interaction.
