A coupled radiation transport particle-in-cell model for fluorescent lamp discharges

Summary form only given, as follows. Resonance trapping and radiation transport in fluorescent lamp discharges are critical for the calculation of efficiency, but many models do not include the effects in evolving the steady state. In this study, we coupled radiation transport into a self-consistent kinetic particle-in-cell simulation. We established a basic model to include radiation transport and nonuniformity of background neutral gas in a one dimensional particle-in-cell code, XPDC1, for the case of single species neutral gas. We treat, electrons and ions with the conventional particle-in-cell method, and the ground state and excited neutral atoms with a fluid model. We include radiation transport in the fluid equations with a simplification, as well as the collisions between neutral and excited atoms, and the nonuniformity of the background gas. The results are compared for the case calculated by the modified code and that calculated by using only the steady state excited atom profile for parameters relevant to a lamp-like discharge in pure argon.
