Compact Planar One-Shot Circular Spark Gap Switch

The fabrication and characterisation of micro spark gap switch for single shot firing applications are given in detailed . A circular switch with triggering electrode is realised on alumina substrate and can be integratable easily with the electronics for ignition applications. Circular switch is realised on 25 mil alumina substrate within substrate diameter of 10 mm. The switch measurement shows having repeatable performance of pulse peak current of around 2000 A and less than 100 ns rise time. This article details the design, development including fabrication aspects of spark switch with trigger capabilities along with characterisation of switch on alumina substrates.
