Abstract: A turret system providing access to the interior of a vacuum vessel integral to a cryostat used for super conducting magnets in MRI systems. The system enabling the movable connection of a neck tube that provides access to the interior of the vacuum vessel when that tube is fixedly attached to the liquified gas container of the cryostat and moves with the liquified gas container, said moveable connection being affected by a supple member attaching said neck tube to said vacuum member, so that relative movement between said liquified gas container and said vacuum vessel does not over-stress said neck tube.
