摘要
采用多级降压收集极是提高行波管效率的有效途径之一。本文在SLAC266 程序的基础上对一支带有二级降压收集极的国外行波管进行了计算,并且将计算结果同实验结果进行了比较。同时用电子注分析仪对降压收集极区电子注的纵向速度分布进行了实验研究,获得了该二级降压收集极的部分工作曲线,并对实验结果进行了分析讨论。
A way to achieve high efficiency for a TWT is to develop multistage depressed collectors(MDCs). In this paper, a foreign TWT′s 2 stage depressed collectors were computed on the bas is of SLAC 266 programme and results were compared with experimental data. The longitudinal velocity distribution within collector region of this tube was measured by means of Electron Beam Analyzer, part of the 2 stage depressed collectors′s operation curve was obtained. At last the experimental results were discussed and analyzed.
