Cryostat assembly having a resilient, heat-conducting connection element

A cryostat assembly comprising:

• an outer container;
• a coil tank located in the outer container and being secured thereto by a first suspension element, the coil tank containing a superconducting magnet coil system to be cooled and a first cryogenic fluid;
• a storage tank located in the outer container and being secured thereto by a second suspension element, the storage tank containing a second cryogenic fluid having a temperature higher than that of the first cryogenic fluid during operation of the magnet coil system;
• a tube element located within the outer container that surrounds a room temperature bore;
• and
• a cover element that is substantially fixed to the tube element and to the first suspension element by substantially thermally conductive connections such that relative movements between the tube element and the coil tank are prevented, and that is connected to the storage tank via a connection element that is substantially thermally conductive and that provides a substantially mechanically decoupled connection that enables relative movement between the cover element and the storage tank.
