Superconducting magnets for recoil separators, wind turbines, and ion beam therapy
Argonne Physics Division Seminar - 25 Nov 2013

Superconducting magnets are widely used in research instruments in many fields of physics, and are now playing an expanding role in applications such as energy and medicine. This talk will cover a recent development in superconducting magnet technology that is currently being implemented for the GANIL SPIRAL2 recoil separator S3. This development is the first large scale application of a mathematical algorithm that enables large aspect ratio multipoles to be fabricated such that the normally troublesome higher order terms in the fringe fields are essentially eliminated. For the SPIRAL2 separator seven large aperture (30-cm warm bore) superconducting multipole triplets are presently under construction in the U.S. using this new coil winding approach. This technology is now already being adopted in the design of a large-scale (10 MW) fully superconducting wind turbine, with coils that are 2-m diameter by 4-m long. Similarly, studies have been initiated to determine the applicability of this coil geometry for superconducting gantries and synchrotrons for cancer therapy with proton and/or carbon beams. The rationale and status of the implementation of this magnet technology in these 3 projects will be presented.
