Adjustable alignment for cryogen venting system for superconducting magnet

A venting system for a superconducting magnet including a cryogen vent adapter pipe attached to the cryostat and connected to an exhaust vent in the enclosure in which the superconducting magnet is installed in order to vent cryogen gas from the cryostat to the atmosphere outside the enclosure, a floating flange alignment assembly positioned between, and sealing, the cryogen vent adapter and the exhaust vent and accommodating misalignments therebetween comprising:

• a flange on said vent adapter;
• a vent pipe including a flange proximate to said flange on said vent adapter and with a plurality of openings spaced about the circumference thereof;
• the inside of said vent pipe being larger than the inside of said vent adapter;
• said openings being larger than the difference between the insides of said vent pipe and said vent adapter;
• a resilient seal positioned between the vent adapter flange and the vent pipe flange;
• a clamping member positioned on the side of said vent pipe flange remote from said resilient seal;
• and
• a plurality of adjustable fasteners extending between said clamping member and said vent pipe flange through said openings to compress said sealing member therebetween and provide a seal between said vent pipe and said vent adapter;
• said vent pipe being radially moveable within the limits of movement of said openings about said fasteners to provide adjustable alignment between said vent pipe and said exhaust vent.
