In order to optimize the gas composition in color ACPDP and improve its performance, a one-dimensional model of gas discharge in ACPDP cell was established. The model was based on the binary fluid description of electron and ion transport and coupled with the Poisson equation and a series of kinetics equation. Using this model, the influence of percentage of Xe content in Penning gas Ne + Xe on the discharge characteristics of ACPDP cell was numerically analyzed. The influence of gas composition ratio on the operating voltage of ACPDP and the UV radiation efficiency during discharge was given . In the calculation process, assuming that the discharge gas is in a state of local equilibrium, the reaction probability of various particles is set as a function of E / p, which is solved by the Boltzmann equation
