Next generation materials for future magnet development at CERN

Looking into the future of CERN's higher energy Accelerators, as in the Future Circular Collider (FCC) and beyond, 16T magnetic fields and above are needed. High Temperature Superconductors (HTS) are now delivering ultra-high fields, with 30 Tesla and higher being achieved by many groups around the world. CERN has the first results of using a high current (10 kA) HTS, with REBCO cables, in an Accelerator type magnet development. This paper presents the multiple technologies and new concepts that were used in the design, build, and testing of a set of high current dipole models. We present the technology advancements in the areas of: advanced modelling, materials used in the magnet construction, quench detection and protection, and field quality. Finally, we take a glimpse at CERN's exciting 20+ Tesla accelerator conceptual magnet designs.
