[IEEE 2018 28th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV) - Greifswald, Germany (2018.9.23-2018.9.28)] 2018 28th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV) - Simulation of the Explosion of a Surface Microprotrusion during a Radio Frequency Breakdown

摘要： The explosion of a surface microprotrusion under the action of a radio frequency electromagnetic field has been numerically simulated. It has been demonstrated that the microexplosion and the subsequent crater formation occur in much the same way as they do in the case of a dc field. The results obtained support the hypothesis that a dc vacuum breakdown and a breakdown initiated by an rf wave incident on a metal surface proceed by the same mechanism.
