Method for determining plasma density in a magnetic field

摘要

A new method is proposed for measuring plasma density based on the direct determination of the phase shift of an electromagnetic wave during the passage of probe radiation through plasma using a broadband oscilloscope. The paper describes a scheme for measuring plasma density up to 4*10~(13) cm~(-3). Examples of using this method to determine the parameters of the inductively coupled plasma and plasma flows in a magnetic field are given.
