A radiation transport coupled particle-in-cell simulation. II. Simulation results in a one-dimensional planar model

The radiation-transport coupled particle-in-cell model is applied to one-di mensional planar model to investigate the radiation trapping phenomena in r elatively high- and low-pressure Ar glow discharges. The radiation intensit y spectra and the total radiation flux are calculated from the radiative ex cited-state profile. The simulation results for Doppler and resonance colli sion broadenings are compared with the eigenmode description of the Holstei n equation, with good agreement. Observed are the effects of radiation trap ping of photons, diffusion, collisional quenching, and step ionization from excited states on the discharge properties.
