Abstract Body

High energy proton colliders towards 100 TeV are proposed these years to study the physics beyond the Standard Model. The colliders call for 16-20 Tesla (T) or even higher accelerator magnets to bend and focus the particle beams. IHEP-CAS has been engaged in developing high field magnet technology with HTS materials like ReBCO and advanced iron based superconductor (IBS). Model coils with different configurations by using the above materials have been developed and tested up to highest 32 T background field to test their current-carrying performance at ultra high field. Development of high current ReBCO and IBS cables with a novel fabricaiton process is ongoing: kA class transposed cables have been successfully fabricated. An overview of the high field magnet program with HTS at IHEP-CAS, present progress and the plan for future will be presented.
