Evolution of the electron transport parameters in He/H2 and Ne/H2 mixtures

Understanding all electron swarm parameters as a function of the reduced electric field is critical for fluid modeling of low pressure electrical discharges. The development of accurate models of electrical discharges in gaseous media requires fundamental data such as electron collision cross sections for particle modeling and electron swarm parameters for fluid modeling. This knowledge is essential for fluid models based on the first and second moments of the electron energy distribution function. To achieve this, we use a specially developed BE solver, BOLSIG+, which is more versatile and provides a steady-state solution of the Boltzmann equation for electrons in a uniform electric field. It is based on the classical two-term expansion for quasi-stationary and oscillating fields, taking into account electron-neutral and electron-electron collisions. In this paper we present the evolution of the transport coefficients as a function of the reduced electric field in He/H2 and Ne/H2 mixtures. In particular, we calculate the electron mobility, the characteristic energy and the ionization coefficient for these mixtures and compare the obtained results with experimental measurements by different authors.
