The 2020 update of the European Strategy for Particle Physics (CERN/3493/C/Rev) has identified a clear and immediate need for a reinforced R&D on advanced accelerator technologies, and in particular high-field superconducting magnets, including high-temperature superconductors.

The High Field Magnets R&D (HFM) Programme is the response that CERN has initiated, in collaboration with National Laboratories from the Member States and Associate Member States and linking possibly beyond to ongoing worldwide efforts, particularly in the US and Japan.

The HFM Programme – broad goals are:

• Develop an Nb3Sn accelerator dipole with 14 T operational field for FCC-hh, giving an energy of 85 TeV c.o.m., with a focus on sustainability, cost versus performance, and large scale production
• Explore the HTS magnet technologies for accelerator applications in the range from 14 T up to 20 T
• Promote the required developments for superconductors
• Highlight the innovative of high field magnets developments, both for particle physics instruments different from FCC, and for societal applications 

Results are needed by the next update of the European Strategy for Particle Physics, expected to take place in the period 2025 to 2026.
