HTS Nuclotron Cable Produced

Two samples of the Nuclotron CORT cable were manufactured and tested for their magnetization loss. The cables were designed to have a critical current of 1350 A at 77.3 K and around 10 kA at 4.2 K. The cable was made using commercial REBCO coated conductor from a non-European manufacturer, which had excellent mechanical properties. The experiments were conducted at IEE Bratislava and at University of Twente in Enschede at 77.3 K and 4.2 K, respectively. The results confirm the expectation that there are negligible electrical contacts between the copper-stabilized tape strands and that it is possible to estimate hysteresis loss analytically for accelerator-magnet-relevant operating conditions.
