High-power X-band amplification from an overmoded three-cavity gyroklystron with a tunable penultimate cavity

Experimental results for a 10 GHz TE/sub 01/ mode three-cavity gyroklystron with a tunable penultimate cavity are presented. The electron beam was produced by a pulse line modulator and a magnetron injection gun which operates to 433 kV and 225 A with 1 mu s flat-top. Three-cavity circuits have prod...

Description
Summary:Experimental results for a 10 GHz TE/sub 01/ mode three-cavity gyroklystron with a tunable penultimate cavity are presented. The electron beam was produced by a pulse line modulator and a magnetron injection gun which operates to 433 kV and 225 A with 1 mu s flat-top. Three-cavity circuits have produced a peak power of 27 MW with efficiency of 32% and pulse energy of 39 J. A maximum gain of 50 dB was achieved at a peak power of 20 MW, and a maximum efficiency of 37% was achieved at a peak power of 16 MW.< >
