The Phillips Laboratory's Rep-Rate Pulser for High-Power Microwave Source Development
Abstract
The Phillips Laboratory has recently received a rep-rate pulser that will be used as a driver for the high power microwave (HPM) sources under development at the lab. The pulser consists of a computer-controlled high-voltage DC power supply, intermediate capacitive store, pulse transf01mer, four 20 omega pulse forming networks (PFN's) in parallel, and a self-breaking output switch. A Macintosh computer running Lab VIEW (National Instruments) software controls the pulser and data acquisition system. As received, the pulser has a 5 omega impedance and can deliver up to a 500 kV, 500 ns pulse to a matched load. The results of the testing of this configuration into a matched resistive load will be given. At the present time, a higher impedance pulser would better serve the Phillips Laboratory, so the pulser has been reconfigured to a single PFN giving a 20 omega output impedance. The results of these test at rep-rates up to 40Hz will also be given.
