THEORETICAL INVESTIGATION OF ELECTRON-NEUTRAL ATOM COLLISION PROCESS AND ELECTRON-TRANSPORT PARAMETERS IN DC GLOW-DISCHARGE OF PLASMA WITH A TRANSVERSE MAGNETIC-FIELD

A Monte Carlo simulation (MCS) technique is used to simulate the catho de sheath region of a helium de glow discharge. In such a simulation, a nonuniform electric held and a transverse uniform magnetic field are considered. When the magnetic field intensity increases from 0 to 800 G, all types of collision considered in this paper are enhanced. This result is in agreement with the experimental result. The results also show that with the increase of magnetic held intensity, the electron transport time, the electron density increase, and the electron mean e nergy decreases.
