Abstract

A four-stage collector system is developed for the experimental gyrotron at the Peter the Great St. Petersburg Polytechnic University based on spatial separation of electrons with different energies in crossed electric and magnetic fields. The conditions of use of this system for the efficient recuperation of electron residual energy in a spent beam are determined. The numerical simulation of the recuperator and the analysis of the electric and magnetic field distribution in the gyrotron collector region are accomplished. Theoretical estimations and trajectory analysis of the helical electron beam show that the system developed provides the electron residual energy recuperation necessary to achieve total gyrotron efficiency over 70%.

摘要

彼得大圣彼得堡理工大学为实验回旋管开发了一种四级收集器系统，该系统基于在交叉电场和磁场中具有不同能量的电子的空间分离。确定使用该系统有效回收废电子束中电子剩余能量的条件。对换热器进行了数值模拟，并对回旋集流器区域内的电场和磁场分布进行了分析。螺旋电子束的理论估计和轨迹分析表明，所开发的系统可提供实现总回旋管效率超过70％所必需的电子剩余能量回热。
