Theory of Negative Resistance in Hollow Cathode Discharges

抄録

The mechanisms of negative resistance of hollow cathode discharges are discussed theoretically based on energy balance. Dependence of radiation intensity from the glow determines the behavior of V-i curves of the discharge. In hollow cathode discharges, radiation is mainly due to sputtered metal atoms of the cathode. Conditions for gas and cathode material have been obtained, under which negative resistance appears.
