ABSTRACT:
An electrodynamic shockwave generator, of the type having a shockwave source formed by an electrically conductive membrane and an electrically driven coil, with the membrane being rapidly repulsed from the coil, causing the creation of a shockwave in an acoustic propagation medium disposed on one side of the membrane, upon the application of a pulse to the coil, wherein at least one of the coil or the membrane contains material which can be placed in a superconducting condition. A coolant, and a member for circulating the coolant are provided for placing the material in at least one of these electrically conductive elements in the superconducting condition.
