Abstract
A new set of swarm data in SF6 and helium were experimentally determined by the pulsed Townsend method over the range 32.24 less than or equal to E/N less than or equal to 563.2 Td (1 Td = 10(-21) V m(2)): the effective ioniz ation coefficient <(alpha)over bar>, the drift velocity V-c and the longitu dinal diffusion coefficient DL The limiting E/N values of SF6-He gas mixtur es were derived from the experiment and found to vary linearly with the SF6 concentration in the mixtures.
