摘要
输出窗的好坏对回旋管的功率容量、可靠性以及使用寿命等性能有直接的影响。在输出窗通过HE11模式的情况下,以氧化铍为输出窗窗片的材料,先进行理论分析,优化设计了无反射窗片的尺寸。然后利用热力学有限元分析软件对输出窗进行了稳态热分析和结构形变分析,得到半径为25mm,厚度为1.25mm的无反射输出窗窗片,能承受的最大连续波功率为210kW左右。为实际工程制管,提供了可靠的理论依据。
The output window is very important to the gyrotron,its quality has a direct impact on the power capacity,reliability as well as service life and other performances of gyrotron.Beryllium oxide was chosen as the output window material,working in HE11 mode,theoretical analysis on it and design the size of the non-reflective window.Then,the steady-state thermal analysis of the situation of output window has been done by the Thermodynamic finite element analysis software,and HE11 mode is used as the operating mode in the numerical simulation.The result shows that the 25 mm radius and 1.25 mm thickness of the non-reflective window piece can withstand the biggest continuous wave power is about 100 kW.The research has provided the reliable theory basis for the actual project tube making,.
