Abstract : High-power electromagnetic devices such as rail guns require pulse power systems that can generate peak powers between 10(exp 8) and 10(exp 11) W and generate electromagnetic fields whose dominant energy spectrum falls between quasi-dc and tens of kilohertz. These fields may be important for electromagnetic compatibility (EMC), and may also be of concern for environmental and biological effects. This paper summarizes the results of the first phase of a U.S. Army Research Laboratory program that deals with the characterization of the electromagnetic fields produced by laboratory rail guns, the results of which can be scaled to operational size systems. Included are discussions of the pulsed power system, measurement techniques, theoretical models, and selected experimental data.
