Magnetic switches were successfully used for pulse compression in the CometII pulsed power module to deliver 2.7 MV and 3.7 TW to a 2 ..cap omega.. matched load. However, the Comet switches suffered interwinding dielectric breakdowns and failed in <100 shots. Initial results from experiments on magnetic switch core insulations indicate that the insulation scheme used in the Comet switches was not optimal and better configurations exist. The Comet magnetic switch failures have been duplicated and studied on the Magnetic Switch Test Module (MSTM), a coaxial, 2 ..cap omega.. PFL driven by a 600 kV Marx generator. The results of these experiments are discussed in detail.
