The authors investigated the recovery properties of a 90-kV, 15-kA multiple site, triggered vacuum spark gap. Triggering was accomplished with a multisite surface flashover plasma source with approximately 60 sites distributed over a 10 cm/sup 2/ area. Gap dimensions were 1-cm spacing by 7.5-cm diameter. Recovery measurements were performed utilizing an inductively recharged double pulse circuit. Under a sinusoidal recharge, the time to a 40-kV recovery occurred in 330 mu s for an average current fall rate approaching 10/sup 10/ A/s. These vacuum spark gap switches may provide an alternative method of high-average-power switching.
