Paper Abstract

Temporal change in electric field strength at the insulator-cathode-vacuum interface accompanied by charging of the insulator have been studied by using a 2D Monte Carlo simulation. The study employed cylindrical insulators and conical insulators. Each of the insulators was made of PMMA, polyimide or Al2O3. The field strength with cylindrical insulators show an abrupt increase, and with conical insulators considerable rapid reduction. Dependencies of the field change on the applied voltage height and material are well demonstrated. Flashovers occur after the simulated field change.
