The collisional-radiative model for an argon atom plasma is applied to analyse elementary processes in the emitter region of hollow cathode and predict the population distribution of excited states inside the emitter region. The modelling results show that the excited species derivate from the Boltzmann distribution. Based on the present model, the dominant kinetic processes of the excited states are investigated in order to better understand the performance of hollow cathode.
