  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.
