Abstract :
A 40 T hybrid magnet is being developed at the High Magnetic Field Laboratory of the Chinese Academy of Sciences. The magnet consists of a resistive insert and a superconducting outsert providing nominally 29 T and 11 T, respectively. The super-conducting outsert with a room temperature bore diameter of 800 mm is composed of three Nb3Sn coils wound from four grades of cable-in-conduit conductor cooled with forced-flow supercritical helium at an inlet temperature of 4.5 K. This paper gives the final design of coils and support structure of the superconducting outsert. Finite element analyses has been performed for normal operational and fault loads. We also describe the cooling scheme, quench detection, and protection.
