Abstract

Abstract

The basic Boltzmann equation in reference is improved. Compared with the basic equation, the improved Boltzmann equation can describe the collision between electron and fundamental state argon more perfectly, and can calculate the electron distribution in the whole energy range. With the basic Boltzmann equation and the improved Boltzmann equation, the high energy electron distributions, whose energy is larger than the first excited state energy (11.56eV), are calculated in argons pumped by electron beam. The analytic formulas on differential ionization cross sections and excitation cross sections are selected for calculation. The calculated results, which include the stationary electron distribution and characteristic time for beams to reach the stationary distributions, are analyzed and
- boltzmann equation,
- electron beam,
- electron distribution function
