Abstract

Provided is a flexible cryostat for use in applications including surrounding high temperature superconductor cabling. The flexible cryostat disclosed here in an embodiment includes a polymer pipe as the outer surface of the cryostat. In an embodiment, both the inner and outer pipes of a cryostat are replaced with polymer pipes which have the same or different thickness and composition. One or both of the polymer pipes can be used in combination with a permeation barrier, which is, in separate embodiments, ethylene vinyl alcohol, or a metallic layer such as aluminum or stainless steel. The flexible polymer pipe can surround the permeation barrier, or the permeation barrier can be positioned at the inner or outer surface of one or both flexible polymer pipes.
