| 摘 要： | 为了开展高功率微波(HPM)馈源输出窗介质击穿实验研究,设计了一种组合型X波段高功率微波(HPM)喇叭馈源击穿实验装置。装置采用变张角喇叭与可移动介质输出窗组合的结构,通过调节变张角喇叭口面与输出窗间的距离,使得介质输出窗内表面电场强度可调。数值模拟结果表明:在满足馈源喇叭驻波比小于1.15,E面和H面基本等化的情况下,当调节变张角喇叭口面与介质输出窗距离在0~400 mm范围内变化时,HPM馈源输出窗上的电场强度变化为32.6~87.0 kV.cm-1,满足了在真空度3×10-3Pa、脉冲宽度20 ns条件下,HPM介质击穿对电场强度变化的要求。根据数值模拟结果,设计加工了HPM介质击穿实验装置,并成功地应用于GW级HPM馈源输出窗介质击穿实验研究。

| Abstract: | A new type of X-band horn feed has been designed for the dielectric breakdown experiment of high power microwave(HPM) feed output window. The feed is made of a horn of variable flare angle and a movable dielectric cover. By adjusting the distance between the horn face and the dielectric cover, the electric field on the dielectric cover can be changed. Numerical simulation results show that under the VSWR less than 1.15 and E-plane being equal to H-plane, the variation of electric field intensity is about 32.6 kV·cm-1 to 87 kV·cm-1 for the distance changing from 0 mm to 400 mm. The need of electric field variation for dielectric breakdown is satisfied, when the degree of vacuum is ３×１０-3 Pa, and the pulse width is 20 ns. The experiment device is designed and processed according to the |
