A detailed collisional-radiative model of low-pressure Hg-Ar positive column was developed. This model was used to predict the change in the lamp spectra under different pulse and lamp fill conditions. The parameters such as the wall temperature, argon pressure, pulse repetition frequency and duty cycle were studied. It was shown that the enhancement of near-UV and visible emissions from a low-pressure Hg-Ar discharge was favored by high wall temperature, high argon pressure, low pulse repetition frequency and small duty cycle.
