Measurement of electron energy and density in an H. F. electrodeless ring discharge

Abstract

The electron temperatureTe and the electron density were measured as functions of the radial distance in a 10 Mc/s electrodeless ring discharge in hydrogen in the pressure range 0.1–0.3 Torr. It was found thatTe remains nearly constant along the radius of the cylindrical vessel. The measured values ofTe have been compared with those observed by other workers and an estimate of the effective electric field in the discharge has been made. From this estimate it has been inferred that even after the first stage of the ring discharge is well established the longitudinal component of the electric field remains of considerable importance. The radial density distribution of the electrons was found to be different from those in an uniform electric field. This deviation in the radial density distribution has been attributed to the influence of the azimuthal electric field.
