要約(日本語): In this study, numerical calculations were performed for the behavior in vacuum arc discharges during current decaying process. The model used in the present work was our originally developed model: the hybrid model with moving particle semi-implicit method and the finite volume method. The model also considered the evaporation of the cathode spot as well as the vapor behavior between the electrodes, as well as the electrode temperature. The current decaying was controlled by regulating the applied voltage between the electrodes. Results indicated that the vacuum arc decayed rapidly by reducing the evaporation rate of the cathode during current decaying.
