Design and Plan of a 10 T HTS Energy Saving Dipole Magnet for the Italian Facility IRIS

IRIS is a large project aiming at building a research infrastructure on applied superconductivity, recently approved in Italy, under the leadership of INFN. In this program we are currently designing an HTS dipole of nearly 1 m of length and of medium size bore, 80 mm x 50 mm, with a central field of 10 T, doubling the record field obtained in HTS dipoles. The article reports the design of the dipole, presents and discusses the main technological choices (coil layout, finite inter-turn resistance, ramping time, etc.) and the R&D plan that will be carried out to support the technology choices and the construction that will be carried out in industry. The dipole will be eventually used as background field in the IRIS cable test facility at Genoa (Italy).
