摘要

螺旋电子束(HEB)形成系统应用最广泛的回旋管包括磁控管注入枪(MIG)和磁压缩区。在该系统中，需要考虑到磁镜反射大横向速度电子、电子枪阴极与磁场平台间陷阱中空间电荷的积累、低频“陷阱”振荡的激发、阴极表面的电子轰击等特殊现象。这些现象会影响HEB质量和限制回旋管参数。本文综述了HEB形成物理过程的实验研究和数值模拟结果。

Experimental study and numerical simulation of electron beam in gyrotron-type electron-optical systems

The most widely used system of helical electron beam (HEB) formation for gyrotron applications includes a magnetron-injection gun (MIG) and magnetic compression region. In this system, it is necessary to take into account such specific phenomena as the reflection of electrons with large transverse velocities from magnetic mirror, the accumulation of the space charge in the trap between gun cathode and magnetic field plateau, the excitation of low-frequency "trap" oscillations, the electron bombardment of cathode surface. These phenomena have an effect on HEB quality and limit gyrotron parameters. In our paper, the results of experimental study and numerical simulation of physical processes accompanying HEB formation are summarized.
