A model of gas spark switch with rough cathode is presented. Utilizing the rough layer thickness and electric enhancement factor to characterize the cathode roughness, the breakdown situation of gas spark switch is studied by probability theory. Influences of gas pressure on the stability, E/p (electric field strength to gas pressure) curve and insulation recovery velocity are analyzed. The study shows when the cathode is rough enough for the mean free path of electron, the switch obtain the highest stability, but when the dimension of coarse structure is close to the mean free path of electron, the switch obtain the best recovery property.
