COUPLING DEVICE FOR A SUPERCONDUCTING MAGNET

15-NM-3381 COUPLING DEVICE FOR A SUPERCONDUCTING MAGNET The device is provided for detachably coupling a power source to a lead pin of the superconducting magnet, the maget being located in a cryostat using helium and the lead pin being in the region of helium vapor. Device includes a split connector formed to engage the pin, an elongated rod joined to the connector in conductive relationship, and a torque tuba positioned around the rod in rotatable relationship. The tube is rotated, a nut joined to the tube and positioned around split connector causes the connector to tightly grip the pin. The device is configured to direct a flow of helium vapor along a path which is proximate to the interface between the connector and pin, to remove heat from the interface and thereby reduce resistance to current flow across the interface. 15-NM-3381 COUPLING DEVICE FOR A SUPERCONDUCTING MAGNET The device is provided for detachably coupling a power source to a lead pin of the superconducting magnet, the maget being located in a cryostat using helium and the lead pin being in the region of helium vapor.
