Two-dimensional PIC simulation of the ion-extraction process in an electrostatic field using different electrode configurations

Abstract

Abstract The ion-extraction process from a finite-size photoplasma is simulated by using a two-dimensional electrostatic particle-in-cell code. To investigate the impact of different electrode configurations on the ion extraction process the parallel plate, wire-type, II-type, and M-type electrode configurations are used. The present study compares the ion extraction time of these electrodes and provides a quantitative audit of the photoions. Through this, it is observed that the M-type electrode configuration extracts more ions in less time than the other electrode configurations. Subsequently, this study quantifies the ion collection on different electrodes, which can be further utilized to design the electrode configuration. Moreover, it gives a systematic study of the ion extraction process in an electrostatic field with different electrode configurations.
