SIMULATION OF ELECTRON SWARMS IN SF6 IN UNIFORM E X B FIELDS

This paper reports electron swarm parameters in SF6 in uniform E x B fields employing a Monte Carlo simulation technique. The parameters studied are transverse and perpendicular drift velocities, magnetic deflection angle, collision frequency, mean energy and effective ionization coefficients for 30 less-than-or-equal-to E/p less-than-or-equal-to 200 V cm-1 Torr-1 and 0 less-than-or-equal-to B/p less-than-or-equal-to 6 x 10 T Torr-1. At a given E/p, application of a magnetic field causes decreases in the transverse drift velocity, the mean energy and the effective ionization coefficient. The validity of the effective reduced electric field concept is also investigated for the evaluated collision frequency, mean energy and effective ionization coefficient.
