A GLOW DISCHARGE PLASMA GENERATOR,

Abstract

This investigation was to determine the capabilities and operating characteristics of a smallscale research facility using a d.c. discharge as the energy source. The goal of the program is to develop a cold plasma source suitable for use with a crossed field accelerator. The apparatus consists of a continuous low temperature electric discharge, the products of which are expanded through a supersonic nozzle into a low pressure chamber. Air has been used as the test gas. The apparatus may be operated continuously. The electricl characteristics of the discharge have been determined from voltage, current and mass flow measurements, and brief impact pressure, current collection and stagnation temperature measurements have been made in the nozzle effluent. The use of a d.c. glow discharge type plasma generator for producing a cold plasma appears feasible. (Author)
