Design of Energy-Saving MgB$_\rm{2}$ Ramped Superconducting Magnets for Particle Beam Lines [Design of Energy-Saving MgB₂ Ramped Superconducting Magnets for Particle Beam Lines = Design of Energy-Saving MgB]

Large accelerator facilities in the medium- and high-energy particle range can consume a significant amount of energy to power the resistive magnets in the beamlines. Depending on the magnet duty cycle, new magnet designs based on superconducting configurations have become increasingly attractive as possible alternatives to energy-intensive resistive solutions. High-temperature superconductor coils made in BCO (rare earth copper oxide) and MgB based cables can be used for both static and ramped magnets thanks to their high energy margin due to the large critical temperature. The University of Milan and INFN-Milano LASA lab. research team are currently working on developing superconducting magnet designs to replace the conventional resistive coils without modifications of the iron yoke of the normal-conducting solution. To highlight the potential of these superconducting materials, we present an estimation of the energy consumption reduction achieved in a MgB superferric dipole ramped magnet case study for the CNAO accelerator complex. Two design iterations, optimized at 10 K and 20 K, are compared with the resistive design demonstrating the benefit on total consumed energy and cost of this type of superconducting magnet solutions for large-scale research facilities.
