Description
The Institute of High Energy Physics (IHEP) of the Chinese Academy of Sciences is pursuing the advanced high field HTS superconducting magnet technology for the next-generation particle accelerators. Significant progresses have been achieved in the past years: world’s first achievement of over 14 T dipole field in the aperture with ReBCO insert coils at 4.2 K. The engineering current density of the Iron Based Superconductor (IBS) has been continuously increased significantly in collaboration with the Institute of Electrical Engineering (IEE) of the Chinese Academy of Sciences; the IBS model solenoids reached 49 A stable operating current at 35 T background field; the transposed IBS cable reached a quench current of 7100 A, and the quench propagation speed of the IBS conductor has also been experimentally measured, showing its superiority over traditional HTS conductors: easy to protect during quench, better mechanical properties and much lower cost. The talk will present the latest promising progress and discuss the possible solutions for the issues to be solved in the next years.
