Superconducting Magnet & Cryostat
AssemblyA niobium-titanium solenoid carrying a persistent current sits in a bath of liquid helium inside a nested dewar, surrounded by a liquid-nitrogen jacket and vacuum spaces; shim coils trim the field to part-per-billion homogeneity. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
