Low Pressure, High Voltage Discharges for the Production of Energetic Electron Beams.

Abstract

The fundamental theories of gas discharges offer widely varying predictions for the relative power input to the negative glow. Calorimetric measurements have been made in a planar helium discharge of the power input to the negative glow relative to the total input power. These measurements show that the limiting efficiency of devices working in this region (e.g., hollow cathode lasers) is approxiamtely 30-40%. To aid in the interpretation of the experimental results a simplified theoretical model was derived. (Author)
