摘要

Numerical simulations by the code of Object-Oriented PIC (Particle-in-Cell) and the Monte Carlo Collision (MCC) method were carried out in order to obtain an insight into the characteristics of plasmas generated by glow discharges in low pressure helium in a four-anode DC glow discharge device. The results show that, the pressure, the external mirror magnetic field, and the virtual breadth of the annular electrode affect the radial distribution of the plasma density and temperature. The simulations are instructive for further experiments.
