SIMULATION OF LIMITING FIELD BEHAVIOR IN ELECTRON SWARMS IN SF6 N2 GAS-MIXTURES

Limiting field behavior of the electron swarms in SF6+N2 mixtures is investigated by a Monte Carlo simulation technique. (E/N)lim values directly obtained from the simulation are given for 5, 10, 20, 40, 60 and 80 SF6 fractional component in the mixture together with the corresponding electron drift velocities and mean energies. Furthermore, in the E/N range of 243 less-than-or-equal-to E/N less-than-or-equal-to 606T(d), effective ionization coefficients and mean energies in SF6+N2 mixtures are also evaluated with fractional SF6 contents of 0, 20, 40, 60, 80 and 100%. The simulation results obtained are compared with the available data in the literature.
