To improve the dielectric strength in a vacuum, spark conditioning through repetitive breakdowns by ac voltage application is an effective method. High-frequency ac conditioning is expected for the higher dielectric strength after conditioning, but the optimized frequency and other conditions for effective ac conditioning have not been clarified. In this article, applied ac voltage frequency and electrode material are investigated as parameters for the dielectric strength improvement by ac condi
