Patent Images
1. A high voltage rail gap switch for a pulse charged source comprising:
- a pair of parallel elongated electrodes, spaced to have a gap between the electrodes;
enclosure means, the electrodes being located in the enclosure means and the enclosure means containing a gas mixture at a total pressure above atmospheric pressure, the gap mixture including SF6, Ar and a small concentration of an organic additive; and
coherent UV radiation source means for directing a pulsed beam through the gas mixture substantially parallel to the pair of electrodes for initiating multichannel breakdown in the gap between the electrodes, the organic additive being matched to the UV radiation wavelength for producing photoionization for the production of a predetermined number of initial electrons in the gap.

Abstract
The laser-triggered high voltage rail gap switch includes two parallel electrodes in a high pressure environment of SF6 and Ar. A pulsed UV laser directs a coherent beam parallel to the electrodes to initiate multichannel breakdown in the gap between the electrodes. This breakdown occurs at a fixed time delay after the laser pulse. This breakdown is enhanced by including an organic additive such as fluorobenzene or tri-n-propylamine in the gas mixture.
