Abstract

At the University of Maryland we have designed¹) and are operating a high power two-cavity TE₀₁ gyroklystron in the 9.7-10.0 GHz range. The target beam power is derived from a 500 kV beam with a current ranging from 120-240 A in 1 μs pulses. The target microwave parameters for this tube include a power level of 15-30 MW with a gain of 25-30 dB. In this paper we describe the initial characterization of the electron gun performance and detail preliminary microwave amplifier experiments. We also discuss modifications recently made to the two cavity circuit to improve stability.
