天鹅绒阴极二极管的实验研究
Experimental study of the diode with velvet cathode
【摘要】 介绍了天鹅绒阴极二极管的结构及天鹅绒阴极的设计 ,给出了二极管参数的测量方法及结果。对 3种不同材料的天鹅绒阴极进行了实验研究 ,获得了大面积均匀电子束 ,并对电子束的横向及径向均匀性进行了诊断。实验结果表明 :二极管工作状态接近的条件下 ,3种材料的天鹅绒阴极所获得的大面积电子束均匀性相近 ,而与天鹅绒的材料基本无关
【Abstract】 The structure of the diode with velvet cathode and the design of the velvet cathode are described; the methods of diode parameter measurement and the results of diode experiment are presented. In the experiment, large area uniform electron beam is generated by three types of velvet cathode, and the uniformity of e beam is diagnosed. The results of diode experiment show that with the similar diode parameter, the uniformity of e beam generated by three types of velvet cathode is similar. In the last, the results of experiment are discussed.
