A burst disk assembly has a burst disk which is interposed within the high pressure relief vent of a superconducting magnet. The burst disk is a composite design constructed of a solid carbon graphite center surrounded by an integrally formed stainless steel ring. A captured burst disk flange insures proper placement and seating of the burst disk during replacement and supports the burst disk so as to prevent it from falling or dropping out of the assembly during replacement of the ruptured burst disk. A deformable gasket contiguous to the burst disk seals the burst disk to the captured burst disk flange when the disk and the flange are pressed together. Attachment bolts are used to provide even application of pressure along the face of the burst disk and the captured burst disk flange.

Superconductive magnet burst disk assembly

An insertion and positioning mechanism to assist in inserting the cryocooler into the sealed cavity of a recondensing superconducting magnet during superconducting operation utilizing guide assembly and slider assembly combinations to resist forces of cryocooler interaction with the magnetic field of the superconducting magnet to avoid misalignment, and to ensure good thermal contact at the cryocooler thermal interfaces.

Magnetic resonance imaging cryocooler positioning mechanism

A pressure relieving venting system for a liquid helium superconducting magnet to vent cryogen gas upon a magnet quench including a burst disk closing the venting system during normal superconducting operation and sandwiched between a peripheral gasket assembly maintained under constant pressure by a plurality of axially extending bolts, spring washers and nut assemblies to preclude helium gas leakage in the absence of the disk bursting under excessive pressure.

Superconducting magnet burst disk venting mechanism

An apparatus and method for precooling a mass to be cooled to a final low temperature by immersion in a cryogenic liquid, e.g. liquefied helium. The gaseous phase of the cryogenic liquid is cooled by heat exchange with a cryogenic liquid having a higher boiling point than the cryogenic liquid within which the mass is to be immersed. The cooled gaseous phase is circulated through a vessel containing the mass, recovered, recooled and recirculated until the mass and its containment vessel are at the desired precooling temperature. Thereafter cryogenic liquid can be introduced into the vessel to immerse the mass.
