A pseudospark (PS) discharge can generate an electron beam with a high current density. The electron beam can be self-focused by an ion channel and transported over a long distance without the need for an external magnetic field. Such features make it attractive to drive millimeter-wave/THz interaction circuits for the generation of high-power radiation from a compact device. This paper presents the experimental results on the generation and transportation of the PS-sourced beam with different cross-sections, as well as the differences of the PS-sourced beam with and without post acceleration. Its application in millimeter-wave/THz sources was demonstrated by the operation of extended interaction oscillators (EIOs) at different frequencies is presented.

伪火花源光束及其在大功率毫米波产生中的应用

伪火花 (PS) 放电可以产生具有高电流密度的电子束。电子束可以通过离子通道自聚焦并在不需要外部磁场的情况下长距离传输。这些特性使得驱动毫米波/太赫兹交互电路以从紧凑型设备产生高功率辐射具有吸引力。本文介绍了不同截面的 PS 源光束的产生和传输的实验结果,以及 PS 源光束有和没有后加速的差异。其在毫米波/太赫兹源中的应用通过扩展交互振荡器 (EIO) 在不同频率下的操作得到了证明。
