摘要
An obstructed glow discharge in helium has been ivestigated both experimentally and by means of a Monte Carlo simulation. The voltage-current characteristics of the discharge have been measured and the spatial distribution of the electric field between the electrodes was determined using Stark spectroscopy. The electric field distribution was also determined by a self-consistent calculation and the results show good agreement with data obtained from Stark measurements. Other discharge parameters (electron multiplication data, energy distribution of electrons absorbed by the anode, energy distribution of ionizing electrons, share of high-energy electrons in ion production, and spatial distribution of ion production) were obtained from the modeling calculations to provide detailed insight into the discharge operation. the effect of the electrode reflection of electrons on the discharge characteristics was also investigated.
