| Abstract: | We addressed the influence of various factors,including the structures of the 2-,3-,and 4-needle electrodes,argon pressure and field distributions,on the glow discharge characteristics.The experimental results show that at a pressure ranging from 0.5 kPa to 2.5 kPa,the electrode geometry strongly affects the breakdown voltage in the glow discharge.For instance,at 0.5 kPa,the maximum difference between the three electrodes was found to be 208 V.The field distributions of the three electrodes were simulated t... |
