| Abstract: | A Plasma-Electrode Pockels'Cell(PEPC)can be used in a high-power laser driving ICF system.In this paper,a one-dimensional model and a two-dimensional model are established and the simulation of a one-pulse-process driving PEPC is given.The relation of the microcosmic process of gas discharge with the parameter of the switch is analyzed.The curves of switch current,plasma-electrode voltage and switch efficiency varied with time and the charged particle density curve are given and compared with the experimental results.It shows that the models are feasible. |
