The authors describe the development and testing of an SF6 insulated, multistage laser-triggered gas switch for use in the Hermes-III accelerator at Sandia National Laboratories. Twenty of these switches are used in Hermes III to transfer energy from intermediate-energy-storage water-dielectric capacitors to the pulse-forming lines (PFLs) and to provide the overall synchronization of the accelerator. The gas switches operate in an oil environment, are charged to a peak voltage between 2.2 MV and 2.4 MV in approximately 1 mu s, and are laser triggered with a root-mean-square (RMS) jitter equal to or less than 2 ns. Both the triggered and untriggered performance of the switch have been investigated. The development test results and initial results from Hermes III are summarized. An average run time spread of 5.7 ns has been obtained in initial testing of half of the twenty Hermes-III switches. This corresponds to an RMS jitter of 1.9 ns. These tests were performed with 1.8 MV across the switch.
