A simulation technique for analysis of transverse evolution of electronswarms in gases was developed based onmoment equations derived from the Boltzmannequation. A numerical calculation of the moment equations for an electron swarm wasperformed using a propagator method and it was demonstrated that the propagatormethod can be used to calculate the higher-order transverse diffusion coefficients stably.Applying a Hermite expansion technique, the electron distribution in real space andother electron swarm parameters were derived as functions of the transverse position.The calculation result was verified by comparisons with those by a Monte Carlosimulation and other methods. Features of the transverse electron swarm evolutionwere presented.
