High power spark gap optimization

This report completes the High Power Spark Gap Optimization program, which was begun under a previous contract with Wright-Patterson AFB. In that program, data was obtained in the power range of 1-5 MW to investigate switch performance at rep-rates up to 500 pps, and at voltages up to 60 kV. In the current program, the main experimental objectives were to demonstrate spark gap power above 5 MW per switch, and raise operating voltage into the 100 kV range.
