Cryostat devices for magnetic resonance imaging and methods for making

A superconducting magnet assembly, comprising:

• one or more superconducting coils;
• at least one coil carrier configured to support the one or more superconducting coils;
• a cryostat, wherein at least one of the one or more superconducting coils is disposed inside the cryostat, the cryostat including:
• an inner vessel configured to accommodate the one or more superconducting coils;
• an outer vessel encompassing the inner vessel;
• and
• a thermal shield configured between the outer vessel and the inner vessel, the thermal shield including:
• an internal cylinder having a first end;
• an external cylinder encompassing the internal cylinder, the external cylinder having a second end;
• a seal head configured between the internal cylinder and the external cylinder, the seal head having a first edge and a second edge;
• and
• a connecting component including a plurality of connectors, each of the plurality of connectors being configured to connect the first end of the internal cylinder with the first edge of the seal head and/or the second end of the external cylinder with the second edge of the seal head.
