测量了不同材料制成的边缘型爆炸发射阴极在BWO基HPM源中工作时的电子束参数和材料消耗。大多数材料在10/sup 4/-10/sup 6/脉冲后表现出发射性能的几种退化和微波发射的减少。石墨阴极在10/sup 7/脉冲后表现出其发射参数的稳定性，并且在10/sup 8/脉冲期间以100-150 pps的脉冲重复率成功地操作。
Electron beam parameters and material consumption were measured for edge-type explosive-emission cathodes made from different materials, working in a BWO-based HPM source, at a large number of pulses. Most of the materials demonstrated several degradation of emission properties and decrease in microwave emission after 10/sup 4/-10/sup 6/ pulses. A graphite cathode demonstrated stabilization of its emission parameters after 10/sup 7/ pulses and successful operation during 10/sup 8/ pulses at a pulse repetition rate of 100-150 pps.
