A 40 T Hybrid Magnet Under Construction in China

The Chinese National Project to develop new high magnetic field facilities began in 2008. It includes the construction of a 40 T hybrid magnet. The magnet will be built at the Chinese High Magnetic Field Laboratory (CHMFL) of the Chinese Academy of Sciences. It consists of a superconducting outsert magnet and a resistive insert magnet. The outsert magnet with a bore diameter of 580 mm at room temperature is expected to provide 11 T. It is composed of two coils: the inner coil is made of cable-in-conduit-conductor (CICC), the outer coil of NbTi CICC. The insert magnet, which will be a 20 MW Florida-Bitter-type resistive magnet with a clear bore diameter of 32 mm, will produce 29 T. The construction of the hybrid magnet is scheduled to be completed in 2013.
