Abstract
Apparatus and methods for low pressure cooling of superconducting magnets, for example, on a magnetic levitated train, through a separate circulation loop from a sealed, unvented thermal reservoir to provide a lightweight cooling system. In a second embodiment, forced flow cooling is directed to the superconducting magnets and shields through a separate circulation loop from a sealed thermal reservoir to further reduce the weight of the cooling system.
