High energy triggered spark gap - has twisted wire triggering electrode mounted inside one of two main spark electrodes

摘要

Triggered spark gap intended to pass about ten joules through its main gap at about 20 kVolts and to provide a low jitter and min. breakdown time using a trigger electrode working at 1 kV and 1 mJ. The main gap consists of two cylindrical electrodes (38, 40) of molybdenum or a tungsten - copper alloy. the overall volume being filled with dry nitrogen at one atmosphere. The trigger electrodes (44, 46) consist of a twisted pair of insulated wires cut across to form a tracking length between the cut surfaces which lie at the level of the inner surface of a hole (39) cut in one of the major electrodes (38).
