根据热核聚变用140 GHz回旋振荡管研制需要, 对高斯模式输出窗进行研究。以化学气相沉积金刚石作为输出窗片的材料, 通过理论分析, 优化设计出低反射、低吸收高斯模式输出窗片的尺寸, 获得窗片半径和厚度分别为46 mm和1.8 mm。通过理论分析各参数对高斯模式透射率的影响, 并利用FEKO软件进行计算验证, 获得高斯模式输出窗设计参数, 从而为热核聚变用回旋振荡管的研究打下技术基础。
Abstract
According to the requirements of 140 GHz gyrotron oscillator in thermonuclear fusion, the study for Gaussian mode output windows is conducted. Chemical Vapour Deposition(CVD) diamond is chosen as the output window material, the size of low reflective and absorption window is designed by theoretical analysis, a radius and thickness of the diamond window are 46 mm and 1.8 mm, respectively. In this paper, the influence on the transmission of Gaussian mode and else parameters are analyzed by using theoretical analysis and FEKO software; finally, the design parameters of Gaussian mode output window are obtained. This work has laid a technical foundation in the application of the gyrotron for thermonuclear fusion.
