W波段回旋行波管电子枪热分析

摘要

利用有限元软件ANSYS对W波段回旋行波管电子枪进行了热应力分析.在给定热子功率下对阴极组件的温度场分布和热形变分布进行了模拟,并通过实验进行验证.测试的温度分布基本与模拟结果基本一致.最后,利用EGUN软件对电子枪形变前后进行了模拟.%Thermal and deformation analysis of W-band gyrotron traveling wave tube amplifier ( Gyro-TWTA) e-lectron gun are carried out by using the finite element code ANSYS in the paper.Temperature distribution and ther-mal deformation of the cathode component at given heater power are simulated.These results are verified experi-mentally in an electron gun.The measured temperature distribution is in agreement with the simulation prediction. Finally,the electron trajectories with and without considering deformation are simulated by EGUN code.
