Abstract

The knowledge of all the electron swarm parameters as a function of the reduced electric field is indispensable for the fluid modeling of electrical discharge at low pressure. In this paper we present the evolution of the swarm parameters as a function of the reduced electric field in the He/H2 and Ne/H2 mixtures. For this we use a BE solver specially designed for this purpose, freely available under the name BOLSIG+, which is more general and easier to use than most other BE available solvers. The solver provides a stable solution state of the BE for the electrons in a uniform electric field, it is based on the conventional two-term approximation. The obtained results are validated through a comparison to experimental swarm parameters already exist in the literature.
