Superconducting Dipoles for Super-FRS: Design, Production, First Measurements
The Super FRS is a two-stage in flight separator to be built next to the site of GSI, Darmstadt, Germany as part of FAIR (Facility for Anti-proton and Ion Research). Its purpose is to create and separate rare isotope beams and to enable access for very short-lived nuclei. Due to its three branches, a wide variety of experiments can be carried out in frame of the NUSTAR collaboration. Due to the large acceptance needed, the magnets of the Super-FRS have to have a large aperture and therefore only a superconducting solution is feasible. The dipole magnets are of superferric design in which the magnetic field is produced by superconducting coils and shaped by the iron yoke. This warm yoke weighs about 50 tons and stays at room temperature; the cryostat with the superconducting coils is embedded into the yoke. The conceptual design of the dipole was developed by CEA, the manufacturing is done by Elytt Energy (Spain), testing takes place at a dedicated test facility at CERN (Switzerland) by a GSI-team in frame of a collaboration contract. In this work we detail the main design features, the production of the first magnets and their testing results.The Super FRS is a two-stage in flight separator to be built next to the site of GSI, Darmstadt, Germany as part of FAIR (Facility for Anti-proton and Ion Research).
