Investigation of Electron Loss Processes in CO2/He/N2 Electric Discharges.
Abstract
An investigation of electron loss processes in electron beam-sustained discharges of an atmospheric pressure gas mixture of 1/1.6/3, CO2/He/N2 in a closed-cycle flow loop was conducted. Steady-state analysis of the discharge current indicates that the discharge is dominated by electron-neutral attachment at rates of approximately 10 to the 6th power sec. minus 1 in the E/N range of 0.5-9 Townsend. Attempts to fit an analytic solution of the electron lifetime equation to the discharge current decay curves were inconclusive due to the slow fall-time of the electron gun relative to the current decay time. Changes in the discharge characteristics due to chemical reactions in the plasma were not significant. (Author)
