Influence of the circuit impedance on an electron beam controlled diffuse discharge with a negative differential conductivity
The use of attaching gases in an externally sustained diffuse discharge opening switch with a low attachment rate at low values of E-italic/N-italic and a high attachment rate at high values of E-italic/N-italic allows the discharge to operate with low losses in the closed switch phase and to achieve fast opening after the sustainment source is turned off. Such an attacher generates a J-italic-E-italic/N-italic characteristic with a negative differential conductivity in an intermediate E-italic/N-italic range. Such a characteristic obstructs the closing process of the discharge if it is operated in a high impedance system. Experiments demonstrating these effects are presented for electron beam sustained discharges in mixtures of argon and C/sub 2/F/sub 6/.
