Abstract

A 2.5D hybrid model is used to numerically study the interaction of a beam with a current of 2.5–7.5 kA and an electron energy of 345–510 keV and terahertz (364–368 GHz) electromagnetic field. It is shown that Bragg reflectors in an electrodynamic system with an overmode ratio of 49 make it possible to significantly suppress backward radiation and multiply increase the radiation power in the direction of the electron beam. Radiation pulses with a power of up to 330 MW are obtained in calculations with disregard of heat loss in the presence of a guiding magnetic field of 6 T.

太赫兹切伦科夫发生器中相对论电子束和电磁场与布拉格反射器的相互作用

摘要利用 2.5D 混合模型对电流为 2.5-7.5 kA、电子能量为 345-510 keV 的电子束与太赫兹（364-368 GHz）电磁场的相互作用进行了数值研究。研究表明，过模比为 49 的电动系统中的布拉格反射器可以显著抑制后向辐射，并成倍增加电子束方向的辐射功率。在不考虑热损耗的情况下，在 6 T 引导磁场的作用下，通过计算可获得功率高达 330 MW 的辐射脉冲。
