The one-dimensional fluid mechanics model of plasma was employed to investigate capacitively coupled discharge in hybrid gas of Helium-oxygen. The relationship between applied voltage and discharge current with gaps of 1.6 mm, 2.4 mm, 3.2 mm was discussed and compared with the experimental data. The simulation results are in good agreement with the experimental voltage versus current curve. It is found that the charge-to-mass ratio of positive ions has certain effect on ions distribution in the process of the capacitively coupled high-pressure glow discharge. The distribution of the positive ion and negative ion of oxygen reaches its peak values at two terminal areas of the main plasma region.
