TEMPERATURE DEPENDENT ELECTRON TRANSPORT STUDIES FOR DIFFUSE DISCHARGE SWITCHING APPLICATIONS.

The electron transport and rate coefficients, such as the electron drift velocity and the electron attachment coefficient for the most promising gas mixtures under study are expected to be functions of temperature, T. Consequently, knowledge of these parameters as a function of T is desirable for modeling the operation of the diffuse discharge switch in practical application. Measurements of these parameters in C//2 F//6 /buffer gas (Ar, CH//4 , N//2 ) mixtures have been made and are reported. An interpretation of these measurements and their significance in repetitively operated diffuse-discharge switching-gas mixtures is outlined.
