Title:
PLUG PIPE FOR NUCLEAR MAGNETIC RESONANCE MAGNET CRYOSTAT
Document Type and Number:
Japanese Patent JPS61153553
Kind Code:
A
Abstract:
A vent tube which is particularly useful for horizontal cryostat penetration comprises a plurality of conduit sections joined by mating rings which facilitate the incorporation of relatively deep circumferential grooves in the conduit sections. Thermal contact springs, preferably in the form of a single strip are disposed in these circumferential grooves so as to provide a means for transfer of thermal energy from the cryostat interior to the exterior either for general refrigeration requirements or for liquefaction of coolant vapor which may have boiled off from the cryostat interior. The cryostat which incorporates the present invention is particularly useful in housing NMR medical diagnostic imaging magnet and coil systems.
