FUNDAMENTAL STUDIES IN THE MICROWAVE PROBING OF MEDIUM AND HIGH-DENSITY PLASMAS.
Abstract
Two methods have been developed to measure the electron density profile of a plasma which varies in one dimension. The methods are based on meas urements of the phase of a microwave signal re flected from the plasma. It is necessary that the plasma frequency somewhere be greater than the microwave probing frequency. It is also necessary that the electron density variation be slow enough so that the WKB approximation to the solution of the wave equation is valid. These conditions are usually met in laboratory plasmas. An experiment on a pulsed hydrogen discharge has been used to apply one of the diagnostic methods. (Author)
