| Abstract: | This paper reported the design and experimental results of a 200kV laser triggered multi stage and multi channel switch. When a quadruple Nd:YAG laser set was used as a trigger source, it was found that the delay decreased exponentially as the charging voltage, pressure or the energy of laser pulse increased when N2 was filled in gaps. The delay increased as the density of SF6 N2 mixtures increased and as the focal length of lens increased for N2, but it is not obvious for SF6 N2 mixture. The discharging phenomenon of multi channel was observed. |
