We present the operating characteristics of a two-cavity third harmonic gyroklystron experiment. The input cavity utilizes a 9.854 GHz TE{sub 011} mode which is driven by a 100 kW magnetron. The TE{sub 031} output cavity has a resonant frequency of 29.57 GHz. The nominal beam voltage and current are 435 kV and 210 A, respectively. The pulse length is about 1 {mu}s and the average ratio of parallel to perpendicular velocity is near one. Peak powers above 1.8 MW are achieved with an efficiency of about 2{percent} and a gain of 14 dB. The theoretical simulations are in good agreement with the experimental results. {copyright} {ital 1996 American Institute of Physics.}
