ELECTRON DENSITY PROFILE
Abstract
Two methods are presented for finding the electron density profile of a plasma which varies in one dimension only. They are based on phase measurements of a microwave signal reflected from the plasma when the plasma frequency is greater than the signal frequency. The methods are applicable when the dimensions of the plasma are such that the W K B approximation to the wave solution is valid. This includes dimensions sufficiently small so as to make time of flight measurements, as used in ionospheric studies, difficult or impractical. Using one of these methods, the electron density distribution in a pulsed hydrogen discharge between 6 x 8 in electrodes placed 18 in apart is found. (Author)
