Pulser for EMP Simulation
Abstract
The project was undertaken to provide a pulser capable of driving a low-impedance array of antennas with a high-peak-power, short risetime pulse to simulate the electrical interference effects of an electromagnetic pulse (EMP). The final pulser produced a 100 kilovolt (kV), 72 kiloamperes (kA) output pulse with a 6 nanosecond (ns) voltage risetime and 42 ns current risetime through a single output switch. Additional experiments showed how multiple output switches could reduce the current risetime to 14 ns with a 9 ns jitter. The output switch was a water-or-air-filled spark gap, and operation in both modes is described. The report also includes design information on a simple and reliable 100 kV d.c. switch, a low-impedance high power dummy load, and voltage and current measuring devices for viewing fast transients.
