Abstract

The switching characteristics of a UV-laser triggered vacuum gap (ULTVG) with a metal target electrode were measured. The gap spacing of the diameter 85-mm copper electrodes was 1.6-mm. The target electrode of the 7-mm in diameter was placed in the hole (8-mm in diameter) of the cathode. The target electrode materials used in this work were Ti and Al. The target electrode and the cathode were connected electrically. An ultraviolet-pulsed laser beam was perpendicularly focused onto the grounded target electrode. The laser was third harmonic beam of Nd:YAG (wavelength 355-nm, energy 5mJ/pulse, beam diameter 2-mm). The operating voltage range for the target electrode ULTVG enlarged more than 11-21% compared with the copper electrode ULTVG and the switching time, 325 ns at 15 kV, was the same in the case of the copper electrode ULTVG.
