Abstract

A superconducting pulsed energy storage coil has been designed and built for the Los Alamos Scientific Laboratory. The energy storage coil specification required an energy store of 0.3 MJ at a current of 10 kA with a discharge time of 2 msec. In addition, the coil structure was required to withstand the forces resulting from a current of 12.5 kA and stored energy of 0.47 MJ. The design inductance of the coil was 6 mH resulting in a design terminal voltage of 40 kV for the 2-msec discharge. The superconductor current density was to exceed two-thirds of the short sample value measured along the load line with cooling provided by immersion in a liquid helium dewar. The losses in the coil due to eddy currents, self-field, and hysteresis were limited by specification to 1.0% during discharge. This efficiency requirement necessitated a nonconducting structure for coil support.
