伪火花放电是一种很有前途的高亮度、高强度电子束脉冲源。PS源电子束具有两个相，初始空心阴极相（HCP）束，随后是导电相（CP）束。在我们的实验中，测量了22 kV，50 A的HCP束，亮度为10（9-10）A m（-2）rad（-2），随后是200 V，200 A的CP束，亮度为10（11-12）A m（-2）rad（-2）。实验已经进行了与应用程序的HCP光束在切伦科夫相互作用没有输入种子波和CP光束后加速。本文设计了一个新的切伦科夫相互作用实验，用20 kW，35 GHz脉冲磁控管的种子波输入，使用相同的PS HCP光束。将提出相互作用的模拟结果，并进一步讨论PS电子束的应用。
A pseudospark (PS) discharge has been shown to be a promising source of high brightness, high intensity electron beam pulses. A PS-sourced electron beam has two phases, an initial hollow cathode phase (HCP) beam followed by a conductive phase (CP) beam. In our experiments, a 22 kV, 50A HCP beam of brightness 10(9-10) A m(-2) rad(-2) followed by a 200 V, 200 A CP beam of brightness 10(11-12) A m(-2) rad(-2) were measured. Experiments have been conducted with the application of a HCP beam in a Cherenkov interaction with no input seed wave and with post-acceleration of the CP beam. In this paper, a new Cherenkov interaction experiment with an input seed wave from a 20 kW, 35 GHz pulsed magnetron has been designed using the same PS HCP beam. Simulation results of the interaction will be presented and further PS electron beam applications will be discussed.
