High Field Magnet Development for HEP in Europe : A Proposal from LDG HFM Expert Panel

The European Laboratory Directors Group (LDG) was mandated by CERN Council in 2021 to oversee the development of an Accelerator R&D Roadmap. To this end, a set of expert panels was convened, covering the five broad areas of accelerator R&D highlighted in the ESPPU. The High Field Magnet (HFM) Panel is proposing a programme to demonstrate Nb3Sn magnet technology for large-scale deployment and to investigate the suitability of high temperature superconductors (HTS) for accelerator magnet applications. A summary of this programme is presented here.
