Experimental studies of a 30 MW two-cavity second harmonic gyroklystron
We report the operating characteristics of a sequence of two-cavity second harmonic K-band gyroklystrons. The TE/sub 011/ input cavity is driven near 9.88 GHz. The first four tubes utilized smooth transition output cavities which resonate at twice the drive frequency in the TE/sub 021/ mode. Peak powers in excess of 30 MW were achieved with efficiencies greater than 28% and large signal gains of 27 dB. The results of an abrupt transition complex TE/sub 01/, TE/sub 02/ mixed mode output cavity are also discussed, as well as the prospect of placing a coaxial insert into the highest power tube.<>
