In order to optimize the structure design of CFETR TF conductor, the influence of rectangle and square conductor on the current transport performance is demonstrated. To analyze the mechanical structure and strands damage caused by different shape, a square and a rectangular experimental conductor were designed and manufactured by ITER TF and CFETR CSMC cable design. The indentation damage and...

Madmax (MAgnetized Disc and Mirror AXion) project is an experiment dedicated to the discovery of the axion particle, the mass of which is expected in the range of 100 µeV. A square-field integral value of 100 T²m² with a 5 % homogeneity over 2 meters along the axis is required. The conductor has been designed to minimize the global magnet cost while fulfilling the following constraints: the...

The conceptual design of the superconducting magnet system for the DEMO tokamak is being carried out in Europe since a few years. The Toroidal Field (TF) coil requirements and main geometrical features have undergone a series of changes, as a consequence of iterations leading to system-level machine optimization. In particular, solutions with 16 or 18 TF coils have been investigated, operating...

The electrical performance of cable-in-conduit conductors made from Nb3Sn superconductor can degrade during operation, depending on the operating parameters selected and the cable pattern and geometry. In this study, we perform a comparative destructive examination on two identical ITER TF conductor sections, one of which is heat-treated but untested, and the second of which has been tested to...

The testing of samples of “cable in conduit conductors” (CICC) made of Nb3Sn and copper strands for ITER toroidal field coils in general cases demonstrated the degradation of current sharing temperature Tcs under cycling electromagnetic loads [1]. This is mostly because of a movement of superconducting strands under Lorentz forces inside a cable that causes the cracking of brittle Nb3Sn...

Superconducting cable is an important component of CICC conductor. The quality of the cable is the guarantee to ensure safe operation of superconducting conductor, and the key step to reduce the degeneration of superconducting conductor performance. The cables will be sustained extremely complex stress during manufacturing process, which is easily cause damage on strands and influent conductor...

The superconducting cables for magnet systems in nuclear fusion reactors usually adopt the Cable-in-Conduit conductor (CICC) concept. CICC cables are known for higher thermal stability compared to other cable designs. Selection of a suitable cable design for higher operational performance still remains a challenge. The maximum magnetic field in future fusion reactors like DEMO and CFETR may...
