Abstract

The results of calculations of the characteristics of electron drift in neon under dc and uniform parallel electric and magnetic fields are presented. The reduced electric fields strengths of 10, 20, 30, 50, and 100 Td at the magnetic field strength up to 10 T and the gas density of 1017 atoms per cm3 are of major interest for gas-discharge plasma physics in many applications. A numerical experiment is used to calculate main drift characteristics, including inelastic processes, and the electron energy balance is analyzed. Main features of the dependence of the transverse diffusion coefficient on the Hall parameter are analyzed, a comparison with known analytical formulas is performed. For the transverse diffusion coefficient, an approximation formula is derived, whose error is identical to the error estimation of the numerical experiment results.
