ABSTRACT:
A spark gap switch having a mid-plane or triggering electrode is brought o a conductive state using a photoconductive switch or other suitable switch, closed by a laser pulse on other pulsed light source. The photoconductive switch is connected between one of the primary electrodes and the mid-plane electrode and brings the potential of the mid-plane electrode to the same potential as the primary electrode when the photoconductive switch is closed. The use of the photoconductive switch permits shorter closing times and eliminates the need for high voltage auxiliary triggering circuits. Plural photoconductive switches, which are triggered in a precise predetermined sequence, improve the operation of Marx generators and other multi-spark gap switch applications.
