Abstract

A crowbar is described which is capable of holding off very high voltage, 80 kV or greater, using two or more mercury-pool ignitrons connected in series. This system will replace a single high-voltage ignitron which has required lengthy processing prior to use and which failed to stand off voltages above 70 kV. It was necessary to perfect a higher voltage device in order to improve the reliability of the crowbar used to protect the high-powered (high voltage) klystron from self-destructive arcs. An experimental version of the crowbar was built and operated. Also an experimental photon generator, using a light-emitting diode and fiber optics and a silicon-controlled rectifier with which to pulse the ignitron, was built and tested. Test results are presented, and the performance has been essentially as predicted. The device will be used on the 400-kW transmitting subsystem.
