High-temperature Rare-Earth Barium Copper Oxide superconductor tapes are considered for devices with time-varying magnetic fields, which means they will be affected by cyclic mechanical loading and AC losses. A recent trend for lowering the AC loss of REBCO tapes is filamentization. The influence of filamentization on the mechanical strength of REBCO tapes is being actively investigated – both...

High Temperature Superconductor Current Leads, HTS-CL are essential components in superconducting fusion machines like ITER, W7-X and JT-60SA. They connect the electrical bus bars from the power supply system with the superconducting feeders of the different coil systems. KIT has designed, manufactured, tested and delivered 16 HTS-CL for W7-X and 26 HTS-CL for JT-60SA. Here, the operation...

16. Experiments on HTS coils in the test facility at CERN: discussion on methods to validate models.Gerard Willering (CERN)12/03/2026, 09:45
A large range of HTS cable and magnet design for high field accelerators is currently being studied and modelled, while the validation of models by experimental results is still rather limited. At the SM18 magnet test facility at CERN various types of HTS magnets have been tested, including insulated, metal insulated and non-insulated coils, with a range of instrumentation including high...

The decreasing cost and expanding production of REBCO tapes make them promising candidates for accelerator magnets operating at high current density and high magnetic field. Within the CHART program supporting accelerator-magnet development, we perform electromagnetic and thermal analyses of the first REBCO subscale (RS1) magnet developed in the MagDev Lab at PSI, designed to enable direct...

During operation, the Cable in Conduit Conductors (CICC) of the ITER Toroidal Field (TF) coils are exposed to severe electromagnetic forces [1]. These forces are in part hoop load and in part crushing load on the strands pressed by the Lorentz-force against the inner wall of the jacket. In addition, the differential thermal contraction between the steel jacket and the superconducting strands...

Current transfers between coated conductors in round cables, such as

CORC cable, are expected to improve the robustness against local
defects in coated conductors. However, no one observed a clear current
transfer. Using an array of small Hall sensors installed in the core
of a round cable to measure the axial magnetic field, we successfully
observed current transfer and confirmed that it...
