Abstract
A cryostat having inner and outer vessels, with a containment vessel disposed in the interior of the cryostat spaced from the inner vessel wall. The containment vessel houses a superconducting coil immersed in a liquid helium bath which is prevented from contacting the inner vessel wall. Primary and secondary shielding arrangements help to intercept heat transferred by gas conduction and radiation. For relatively high power operation wherein the coil is charged and discharged frequently, the inner and outer vessels are fabricated of a non-magnetic composite material.
