Abstract

We present experimental results of a 10 GHz TE₀₁ mode three-cavity gyroklystron. The beam is produced by a pulse line modulator and magnetron injection gun, which can operate to 433 kV and 225 A with 1 μs flat-top and at a rep rate of 3 Hz. Microwave power is measured by a mode-selective directional coupler and flowing methanol calorimeter. Mode purity is determined by a large anechoic chamber. Initial testing of the first three-cavity circuit has produced a peak power of 23 MW with efficiency of 27% and pulse energy of 36 J. We have a maximum gain of 39 dB at a peak power of 21 MW.
