摘要

采用数值模拟的方法，比较了两种测量爆炸发射阴极形成的大电流相对论电子束宽带电磁噪声功率的方法。仿真结果表明，实验结果的两个数量级差异（持续时间为几纳秒的脉冲为几兆瓦，持续时间为数百纳秒的脉冲为几十千瓦）是由爆炸发射阴极操作不同阶段的噪声本身的性质引起的，而不是由测量方法的差异引起的。

On Noise Power in High-Current Relativistic Electron Beams Formed by Explosive-Emission Cathodes

Numerical simulation is used to compare two methods for measuring power of wideband electromagnetic noise in experimental facilities with high-current relativistic electron beams formed by explosive-emission cathodes. The simulation shows that the difference in the experimental results by two orders of magnitude—several megawatts for pulses with a duration of few nanoseconds and tens of kilowatts for pulses with a duration of hundreds of nanoseconds—arises from the nature of the noise itself at different stages of the explosive-emission cathode operation rather than from difference of the measurement methods.
