Design and first results of a 4 MA strip line generator to produce magnetic pressure for material studies
Summary form only given. The main goal of the presented HPP generator is to produce quasi-isentropic magnetic pressure ramps. This magnetic pressure should reach several hundreds of kbar for a generic copper sample of several tens of mm/sup 2/. This device will be a proof of principle of the use of...

Summary: | Summary form only given. The main goal of the presented HPP generator is to produce quasi-isentropic magnetic pressure ramps. This magnetic pressure should reach several hundreds of kbar for a generic copper sample of several tens of mm/sup 2/. This device will be a proof of principle of the use of compact (and then low cost) HPP generator to study high pressure dynamic behavior of materials. The peak current will reach at least 4 MA for a rise time varying from 180 ns to 300 ns. The dimensions of the generator will be a 5m/spl times/5m square based on a strip line design with solid dielectric insulation. 26 to 28 elementary generators made by HCEI, including multi gaps, multi channels switches, will be connected in parallel around the strip line. The technology used allows compactness of the generator and minimizes side equipment, avoiding use of pressurized gas, oil and vacuum. A peaking capacitor can be used to shape the current pulse. The paper present the features and the technology of the generator. Also, the first experimental results will be shown and the potentialities for material studies will be described. |
