Switching characteristics of sealed-off triggered vacuum gaps (TVG's) were examined from the viewpoint of a high repetition rate at high current discharge. With a triggered energyof 11 J, it was possible to fire the main gap in both the anode and cathode modes of operation.In repetitive discharge experiments, the TVG-tube was put in the center of the cylindricalconductor and the switching tube inductance was about 27 nH. The TVG-tube was confirmed tohave capabilities for 1000 shots with a pulse current of 120 kA and a high repetition rate of5 Hz. These experimental results indicated that the TVG-tube is a potential repetitive closingswitch for the plasma X-ray source.
