A 40 kV, 3.1 /spl Omega/ PFN for the Main Injector abort kicker

The Main Injector abort kicker system has been run at full voltage. The system was required to operate with a PFN to meet specifications. The system was designed to operate in air to allow for easier maintenance. The topology chosen has the thyratron cathode grounded, a grounded PFN and a floating pulse transformer. The system is also required to have low EMI because of the proximity of low level controls. Several problems related to the pulse transformer and to operation in air are addressed and some solutions are presented.
