Abstract

Abstract: A method for measuring the plasma potential with emissive probes, the “droop” method, is presented in this paper．The plasma space potential for the microwave plasma source of double “ECR” chamber has been measured in this method．The radial distribution of the plasma space potential and its variation with pressure and the microwave power has been derived∙

Key words: Floating potential, Plasma space potential

摘要： 介绍了一种用发射探针测量等离子体空间电位的方法——“降落法”，并利用这种方法测量了双共振腔 ECR 微波等离子体源的空间电位分布，从中得到该等离子体内部的一些电场信息。给出了不同微波功率和不同压强下 Ar 等离子体空间电位的分布情况。
