Abstract In order to achieve the two-dimensional simulation of gas discharge under limited conditions, a simulation program based on Matlab has been developed in the paper, and utilized to verify the discharge process of argon under direct current and low pressure. Electronic speed was initialized through Maxwell equations and the results were verified. The occurrence of electron avalanche in the process of argon discharge was verified by extracting the change trend of the number of electrons in the 50 time steps, and the production of anode sheath was observed through the distribution of electron position at the end of the 100 time step. According to the solution of Poisson’s equation to the 200 step and 300 step, the solution of Poisson's equation in the 200 step was sufficient under the simulated conditions in this paper. The diagram of temperature distribution given by the root mean square treatments of the electron velocity successfully verified the experimental phenomena that the temperature near the anode plate was higher in the DC argon discharge. Thus, the two-dimensional PIC/MCC program based on Matlab can satisfactorily simulate the gas discharge.
