Short Time Energy

For shock waves produced by special wire explosions the short time energy input condition of the theories of Lin, Sakurai and Vlases-Jones is fairly good fulfilled. In these cases the shock wave energies can be easily determined from the expansion velocity of the waves. Variation of the parameters of the discharge circuit show, how these parameters should be chosen in order to get a maximum transfer of energy either to the shock waves or to the wire material.

<div>Poster contribution to the 26th International Conference on Magnet Technology (MT26) in Vancouver, Canada, September 22-27, 2019. paper was submitted to the MT26 special issue of the IEEE Transactions on Applied Superconductivity.</div><div><br></div><div>Abstract: Inductive pulsed power generators apply coils as<br>powerful short time energy storage which is an ordinary mean to deliver pulses of high power to loads like electromagnetic accelerators. This article deals with the design, simulation, construction, electrical characterization and a pulsed stress test of a modular toroidal coil. The coil was made from 180 D-shaped copper discs and has an approximate inductance of 1mH (f > 50 Hz) and frequency dependent resistance according to 3.88 mOhm Sqrt(f) + 5 mOhm. Its height, diameter and weight is 0.4 m, 1 m and 1 ton respectively. It is designed to store more than 1 MJ<br>of energy.<br></div>
