Abstract : Electrostatic probe measurements along the axis of the low-voltage arc in neon, xenon and hydrogen are continuing; curves are given of the maximum electron density, maximum plasma potential and discharge voltage as a function of neon pressure for a four-ampere, low-voltage arc with constant spacing. The curves indicate that the maximum electron density and the discharge voltage increase with gas pressure; the maximum plasma potential in the discharge remains constant at slightly less than the excitation potential of the gas. A study was made of the necessary changes in the experimental system in order to include cesium vapor in this low-voltage arc study. Checkout of the computer program for the Monte Carlo simulation of a plasma diode operating in the low-voltage arc mode is currently under way. A method of statistical analysis of the acquired data has been developed. (Author)
