To simulate the experiments of the pulsed Townsend in the SF6-N2 gas mixtures and obtain the distributions of the electronic energies in different states
the development of the electron avalanche in SF6-N2 gas mixtures is traced using the Monte Carlo simulation for the ratio of electric field to gas density(250 ~ 450) Td.The effective ionization coefficients
the distributions of the electronic energies and critical electric field of gas mixtures are directly obtained from the simulation
