Paper Abstract

Both a small signal approach for ac space-charge effects on beam bunching in the gyroklystron drift tube and nonlinear self-consistent field slow-time scale ballistic theory are applied to investigate the wideband gyroklystron gain including the beam velocity spread effects. The analysis of ac space-charge effects on beam bunching, based on the parameters of existing electron guns, results in the possibility of the wideband amplification in the tremendously high gain gyroklystron using the drift tube of the approximately 20 (lambda) length or more. The test results of the IAP two-stage, 16kV, 3A, 20dB gyroklystron operating in TE011 mode are presented and discussed. Also, the test results of the Tory TE011 three-stage, 50kV, 14A gyroklystron are discussed. Having the first drift tube of the approximately 10 (lambda) length, this gyroklystron demonstrates the 40dB gain, the 1.3% bandwidth, and the 230kW output saturated power.
