The objective of this book is to acquaint the reader with explosive driven pulsed power devices, theory and applications. This includes those devices that convert the chemical energy stored in high explosives into electrical energy and that use shock waves generated by the explosives to release the energy stored in ferromagnetic or ferroelectric materials in the form of electrical energy. The reader might well ask why one should use explosive driven pulsed power for any application, since it is inherently single shot in nature. There are really two very different answers to this question. First, explosives store the greatest amount of energy per unit mass (4MJ/kg) or per unit.
