| 摘 要： | 利用等效电路理论,初步设计了窗片厚度为1.32mm的回旋行波管盒型输出窗,再加入感性膜片,更改窗片形状,最终设计出了能承受25kW平均功率、相对带宽达到14%、窗片厚度达到1.7mm的Q波段新型宽频带回旋行波管盒型输出窗;采用高频软件HFSS与有限元分析软件ANSYS协同仿真的新方法对回旋行波管盒型窗进行热特性研究表明,盒型窗理论上功率容量达到62kW平均功率,说明输出窗窗片承受25kW平均功率的可行性,窗片中心与边缘的温差为66℃,没有达到陶瓷窗片的临界温差158℃,验证了新型盒型窗设计的合理性。

| Abstract: | Using the equivalent circuit theory, we design a pill-box output window for Q-band high power gyrotron traveling wave tube (gyro-TWT) with a thickness of 1.32 mm. Through inserting the inductive diaphragms and changing the shape of the window, the designed pill-box output window can withstand an average power of 25 kW, the relative bandwidth is 14%, and its thickness is changed to 1.7 mm. This paper uses a high frequency software HFSS combined with a new method of collaborative simulation of finite element analysis software ANSYS to simulate the thermal characteristics of the pill-box output window. It shows that the new-type of pill-box can withstand an average power capacity of 25 kW at the bandwidth, and the temperature difference between center and edge of the window is 66 ℃, while the tolerance temperature is 158 ℃ of the ceramic window. Thus, it verifies the rationality of the new pill-box output window for Q-band high power gyro-TWT. |
