Title: Electron Energy Distributions in Various Discharges

Results are given for dc discharges in inert gases with and without mercury vapor present. Tubes of 34 mm i.d. with filling pressures of 1.0 to 7 Torr and arc currents from 0.2 to 1.5 A were used. At the higher currents, a Maxwellian distribution (MD) was always found for electron energies insufficient for inelastic collision and was sometimes present at higher energies. Deviations from a MD increase with increasing mean energy of the electrons and with increasing distance from the axis of the discharge. The latter effect was enhanced in a tube with neon plus 0.25% Kr in which radial cataphoresis kept the krypton near the tube wall.Read More
