Calculation of Electron Swarm Parameters in Ar/H2 and Kr/H2 Mixtures

To develop the modeling of electrical discharges in a gaseous medium, it must to know a numbers of basic data such as: the electron collision cross sections for particle modeling or the electron swarm parameters in the case of the fluid modeling. The knowledge of all the electron swarm parameters as a function of the reduced electric field is indispensable for the fluid models based on the first and the second moment of the electron energy distribution function. The objective of this work is to calculate the mobility, the characteristic energy, and the ionization coefficient in the case of the mixtures Ar/H2 and Kr/H2. The results obtained will be compared with measurements already made by different authors.

Calculation of the Electron Swarm Parameters in He/H2 and Ne/H2 Mixtures

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.
