摘要
通过实验和粒子模拟相结合的方法对L波段MILO在低真空度下的工作特性进行了研究。实验和模拟中都观察到了低真空情况下MILO的功率增强和频率升高,在2 Pa内,粒子模拟中没有观察到脉冲缩短现象,实验上脉宽略有下降,但是辐射微波单脉冲能量增大,MILO工作性能在低真空下有一定提高。研究发现适量等离子体填充同样可以改善MILO工作性能。
Plasma filling has been widely used as an effective method to improve the performance of Cerenkov devices. In the process of designing a hard-tube MILO, we found that it might improve the output power largely without obvious pulse shortening at a low vacuum range of 0.01-2 Pa, which had not been reported on MILO previously. Experimental method associated with PIC simulation was adopted to investigate the performance of an L band ladder cathode MILO at low vacuum levels. The result tells that the MILO could work better at low vacuum levels.
