Superconducting magnet system with cooling assembly

A superconducting magnet system, comprising:

• a coil former comprising a first surface;
• a plurality of superconducting coils supported by the coil former;
• and
• one or more cooling assemblies in thermal contact with the coil former, each cooling assembly of the one or more cooling assemblies comprising:
• a housing defining an aperture extending therethrough;
• one or more-cooling-tubes located within the housing for receiving a cryogen passed therethrough;
• and
• a second surface attached on the first surface of the coil former;
• and
• a fastener removably received within the aperture in the housing and extending through the first surface of the coil former to detachably mount the cooling assembly on the coil former, the cooling assembly forming at least one cooling circuit therein.
