A hybrid type direct simulation Monte Carlo (DSMC) method was applied to a one- dimensional electrostatic plasma in Argon/Nitrogen mixtures to simulate neutral and ion transport in a radial symmetric inductively coupled plasma. The ambi-polar electrostatic field obtained from the measured plasma density profile was imposed in the simulation, and electrons were treated as background particles with measured electron density and temperature profiles. Neutral gas depletion observed in both the experiment and simulation is in excellent agreement and indicates that gas heating and the required pressure balance is responsible. The gas heating is mainly due to ion-neutral collisions with the ions accelerated by the ambi-polar electric field and neutral collisions with Frank-Condon dissociated atoms.
