Abstract
The conceptual design of China fusion engineering test reactor (CFETR) is now ongoing. Its toroidal field magnets with a peak field of 15 T which require a new conductor testing facility with higher background magnetic field to test and evaluate the performance of these conductors. As part of the study of CFETR, the facility named Super X (SUPERconducting eXperiment) is planning to be constructed at ASIPP and a conceptual design activity related is going on in parallel. The background magnetic field of the facility is generated by three concentric pairs of split coils with a bore of 600mm diameter, inner coil (IC, peak field of 15.6 T), middle coil (MC, 13.3 T), and outer coil (OC, 10 T) in which IC and MC are connected in series with a nominal operating current of 7.9 KA, while OC operates at 13.5 KA. Each split pair coil is made of its own distinctive rectangular shaped cable-in-conduit conductor (CICC). The design and preliminary results of electro-magnetic optimization and structural mechanical analysis for the background magnet system are presented.
