Description
To explore physics beyond the capabilities of the LHC and its High-Luminosity Upgrade (HL-LHC), particle physicists are aiming for higher-performance accelerators that allow more precise measurements or operate at higher energies and intensities. The last update of the European Strategy for Particle Physics highlighted the urgent need for enhanced research and development on advanced accelerator technologies, particularly high-field superconducting magnets, including High Temperature Superconductors (HTS). In response, CERN launched the High Field Magnets (HFM) R&D Programme in collaboration with national laboratories. The programme aims to explore the performance limits of Low Temperature Superconductor (LTS) accelerator magnets, investigate the new HTS magnet technologies beyond the capabilities of Nb3Sn, and develop the next generation of accelerator magnets for future colliders. This presentation will be focused on the progress of the FalconD project, developed by INFN in collaboration with CERN (12 T cos-theta single aperture dipole magnet). Following this work, a new agreement is in process of being signed between CERN and INFN to carry on the activities, in particular we will be engaged in the design, manufacture, and cold tests of a single aperture, 4-layer short model magnet (less than 2 meters), featuring a cos-theta configuration and generating a bore field of 14 T. Within the HFM program, different configurations of HTS dipole magnets designed for accelerator applications will be studied and assessed as well. HTS technology is making significant progress, with reductions in conductor cost, improved quality, and better availability. However, it remains uncertain if HTS can be developed into conductors suitable for accelerator-quality magnets. The focus of the collaboration agreement between CERN and INFN is also to explore a range of HTS dipole designs, assessing their potential to become high-quality accelerator magnets. Among the various designs, the most promising one will be selected for engineering, manufacturing, and testing at various temperatures to thoroughly assess their suitability as candidates for accelerator magnets. The main characteristics of this dipole subscale model will be determined by the collaboration parties, with the broad goal of achieving 10 T at 20 K and a coil aperture of approximately 50 mm.
