摘　　要：输出窗是回旋管非常重要的部件之一,它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.在输出窗输出TE01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,然后在ANSYS软件里建立了输出窗的有限元模型,进行了稳态热及形变分析.仿真结果表明,氧化铍的导热性能非常好,适合作大功率微波器件的输出窗片.The output window is one of very important parts of the gyrotron,and its quality has the influences on gyrotron power capacity,reliability as well as service life and other performance directly.The beryllia is used as the material to study the output window.The steady-state thermal analysis of the situation of output window has been done by the commercial soft,and TE01mode is used as the operating mode in the numerical simulation.The results show that the thermal conductivity of beryllia is perfect and suits to make the output window of high power microwave device.
