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.

氖漂移过程中纵向磁场对电子扩散的影响

摘要

介绍了直流和均匀平行电场和磁场下氖中电子漂移特性的计算结果。在高达 10 T 的磁场强度和 10 ^{17 个}原子/cm ³的气体密度下，降低的电场强度分别为 10、20、30、50 和 100 Td气体放电等离子体物理学在许多应用中具有重要意义。通过数值实验计算了包括非弹性过程在内的主要漂移特性，并分析了电子能量平衡。分析了横向扩散系数对霍尔参数依赖性的主要特征，并与已知的解析公式进行了比较。对于横向扩散系数，推导出近似公式，其误差与数值实验结果的误差估计相同。
