Conventional superconducting magnet systems supply coolant centrally from a refrigerating system and have a current input provided separately in each case or through special magnets at the beginning and end of a section formed from superconducting electromagnets. The superconducting magnet system of the invention, which is to be used in particular for accelerator units, provides a control cryostat between the refrigerating system and the magnet cryostats encompassing the magnet coils of the electromagnets. The control cryostat at the same time has a current supply lead from which the magnet cryostats associated with the respective control cryostat are supplied with the current necessary for excitation through superconducting cables.

A cooling system for indirectly cooled superconducting magnets of a superconducting winding, includes a winding form having canals formed therein through which liquid helium flows, the canals including a lower feed canal, an upper collecting canal and mutually parallel cooling canals interconnecting the feed and collecting canals in close thermal contact with the superconducting winding, a helium supply vessel disposed opposite to and elevated with respect to the winding form, the helium supply vessel having an outlet and a connecting stub, an outgoing line connected between the feed canal and the outlet, and a return line connected between the collecting canal and the connecting stub.

Cooling system for indirectly cooled superconducting magnets

A method of making a superconducting coil from a superconducting wire includes the step of winding the wire to form a coil. Prior to the winding step, the wire is submitted to repeated tension-stressing of a predetermined stretch and a predetermined number of cycles, in order to reduce the 'training' of the superconducting coil.
