Theoretical Investigations of Time-Dependent Behavior of Electrons in Gases.

Abstract

The major aim of our research investigations has been to develop new algorithms and the corresponding computer codes for exact numerical solutions of the time dependent Boltzmann equation for the transport of electrons (and other charged particles) in gases subjected to external electric fields of arbitrary strengths. The electron velocity distribution function obtained as a solution of the Boltzmann equation is used to calculate a set of experimentally measurable swarm parameters for the transport of electrons in actual pure gases or in gas mixtures subjected to static or time dependent external electric fields. A direct comparison of the calculated swarm parameters with the corresponding experimental values provides a useful check on the validity and accuracy of the results obtained using the present codes. It is especially useful to have a general computer program for calculating the theoretical values of the electron swarm parameters for gases for which there are, as yet, no experimental values or for which direct laboratory experiments are simply not feasible.
