An investigation of the positive column of a Cd-Ne glow discharge: II. Afterglow

The afterglow of a Cd-Ne glow discharge is investigated theoretically and e xperimentally, The time-dependent electron Boltzmann equation and the balan ce equations for the Cd excited stales and charged particles have been self -consistently solved. The temporal relaxation of the electron energy distri bution function, electron, and cadmium excited states densities is reported and the influence of neon and cadmium vapor pressure on the plasma charact eristics in the afterglow is studied. The modeling compares favorably with experimental results.
