Study on Initial Stage of Gas Discharge by Numerical Method
The progress and characteristics of initial stage of gas discharge is studied in this paper by numerical simulation. A program based on the FE-FCT method in its full two-dimension form is developed and employed for the solution of transport equations of charged species under the effect of space-charge electric field. The initial stage of gas discharge between parallel plate electrodes, including the development of avalanche and progression of Townsend or streamer discharge are presented. The influences of length of gap and applied electric field on the mechanism and process of breakdown are analyzed and the breakdown voltage and formative time of discharge are predicted by the numerical method, and is well agree with the experimental result. The actions of cathode secondary emission on discharge are investigated, and photoemission is found to be more efficient than ion-electron emission.
