摘要
输出窗是真空电子器件的关键部件。本文对中心频率为0.216THz折叠波导行波管的输出窗进行了理论设计,并用CST对其结构参数进行优化,得到了基于蓝宝石窗片的盒型窗结构。分析了窗片表面电场分布以及结构参数对盒型窗电压驻波比的影响,确定了输出窗各尺寸加工的公差,当主要结构参数在±0.01mm范围内变化时,窗的电压驻波比仍小于1.2。本文的研究工作在后续研制0.216THz的行波管输出窗得到了应用。
The output window is the key component of the vacuum electronic device. In this paper, the output window of the folded waveguide TWT with a central frequency of 0.216 THz is designed, and the structural parameters were optimized by CST. Then we get the pill-box window's structure based on sapphire. We analyzed the electric field distribution and the influence of structure parameters on the VSWR. We also determined the tolerance of each parameter of the output window. The VSWR is below 1.2 when the main structural parameters range at ±0.01 mm. The research work in this paper is applied to the output window of the 0.216 THz folded waveguide TWT.
