Limiting crossed magnetic fields in Townsend discharges of Ar+SF/sub 6/ binary mixtures

Abstract

The limiting crossed magnetic fields in Townsend discharges of Ar+SF/sub 6/ binary mixtures are evaluated together with pulsed-Townsend mean energies and electron drift velocities along the applied electric field direction. The results are presented in the E/N range of 200 Td-600 Td with SF/sub 6/ content in the mixture varying from 1% to 75% for the corresponding limiting magnetic field.
