    Abstract

    Sharing similarities with the GEPI puiser which is dedicated to Isentropic Compression Experiments (ICE), VELOCE, an even more compact electrical puiser, has been designed and built in duplicate for SNL and WSU. This type of machine complements gun and laser facilities in the study of material response. In order to achieve a broad loading capability and fast turn around, the design is built around a solid dielectric transmission line to couple current from low inductance capacitors and electrically triggered switches. Peaking capacitors enhanced by a low inductance, multi-channel sharpening switch reduce the quarter period of the puiser to about 470 ns (0-100%). Gas mixtures in the switch cavity and inductances in parallel allow modification of the shape of the induced pressure wave. At 80kV of charge voltage, the peak current can reach 3.5MA. Design of the puiser, range of pressures and velocities, as well as potential applications are presented. A consistent numerical tool developed for pulsers design based on a circuit code coupled to a 1D MHD code is also introduced.
