Abstract

A proposed plasma physics experiment will make use of a magnetically levitated. mechanically isolated superconducting coil. Enclosed within a toroidal dewar that is sealed and operated isochorically within a vacuum vessel [1]; this coil will need to be recooled and re-energized daily. The minor diameter of the dewar is limited by the requirements of the plasma experiment, and the cryogenic design must therefore seek to optimize the performance of this fixed-volume system.
