The Present Status and Progress of the CHMFL 40 T Hybrid Magnet

Abstract

The development of new high magnetic field facilities in the Chinese High Magnet Field Laboratory (CHMFL) will soon be completed according to the present situation. For the construction of the 40 T hybrid magnet, which will be the highest magnetic field facility in China, great progress has been achieved so far, for example, the engineering design of the resistive insert composed of six Florida-Bitter-type coils has been completed and part of the Bitter disks has been punched in Shanghai, and significant R & D progress on the design and manufacture of the superconducting outsert has been made, and the other main components of the superconducting outsert, such as?cryostat, 80 K thermal shield, vacuum pumping units, busbars, a pair of 16 kA HTS leads, overpressure protection device and so on, have been manufactured. The recent development of the CHMFL 40 T hybrid magnet is introduced in detail.
