摘要

本文研究了在振幅为~ 300 kV、脉冲宽度为~ 10 ~ 9、脉冲重复频率高达3.5 kHz的电压脉冲下石墨阴极的发射特性。电子束的峰值功率为0.6 GW，平均功率高达3kw。单脉冲电流能量为~ 1 j，分析了电流发射延迟与束流转移电荷的动力学关系。用扫描电镜对阴极表面形貌进行了检测。

Study of explosive-emissive graphite cathodes in the pulsed-periodic operating regime

Emission properties of a graphite cathode supplied by voltage pulses with an amplitude of ˜300 kV, a pulse width of ˜10-9 and a pulse repetition frequency of up to 3.5 kHz, have been studied. The electron beam had a peak power of 0.6 GW and an average power of up to 3 kW. A single current pulse had energy of ˜1 J. Dynamics of the current emission delay in correlation with the charge transferred by the beam has been analyzed. The cathode surface morphology was checked with SEM.
