Redundant cryorefrigerator system for a refrigerated superconductive magnet

摘要

A cryorefrigerator mount for a refrigerated superconductive magnet is disclosed. In particular, a cryorefrigerator system has two separate cryorefrigerators such that one of the cryorefrigertors contacts and cools the magnet while the other cryorefrigerator is held in a raised, standby position. If the first cryorefrigerator malfunctions and can no longer cool the magnet, the second cryorefrigerator is lowered to contact and cool the magnet. The first cryorefrigerator is then raised so it can be repaired, serviced or replaced.
