Spatiotemporal development of charged particle swarms in gases under the influence of electric and magnetic fields

POSTER

Abstract

In this work we present a systematic investigation of the synergism of magnetic field and non-conservative collisional processes on spatially resolved transport data of charged particle swarms in neutral gases under the influence of electric and magnetic fields crossed at arbitrary angles. Spatiotemporal development of the swarm is followed by a Monte Carlo simulation technique in certain collisional models of ionization and attachment over a range of angles between the fields and field strengths. Independently of the field configuration, it is found that spatial density profiles of the swarm relax to a Gaussian profile after a sufficient time with a spatial segregation of groups with different average energies resulting in a linear profile.
