Abstract : Disclosed is a high-voltage, high-current, multichannel, optically-triggered switch with the potential for improved lifetime of operation. Triggering of the switch is accomplished by ultraviolet illumination of multiple cathode apertures via fiber-optic cables. The trigger optics for each channel, being composed of a fiber-optic cable terminated by some collimating optics, are protected from damaging metalization by enclosing them in an angled metal or dielectric tubes in the cathode backspace. The use of collimating optics at the output of the fiber allows the fiber to be recessed inside the shield tube, providing further protection from discharge by-products
