TLDR
In this paper, a new 2.8m long CORC CICC has been prepared to replace a degraded sample, which has a design critical current of 100kA at 10 T and 4.5 K at 4 K. The voids between CORC strands in the new sample are filled with solder alloy to provide increased mechanical support to the strands.Abstract:
In recent years, three unique Re BCO-CORC CICC samples with six-around-one cable layout were developed as technology demonstrators at CERN in collaboration with Advanced Conductor Technologies. The tests of these conductors at low temperature in external magnetic field yielded very promising results, but also showed several issues requiring improvement. A new 2.8 m long CORC CICC has been prepared to replace a degraded sample. The voids between CORC strands in the new sample are filled with solder alloy to provide increased mechanical support to the strands, however, this yielded an additional set of new challenges. The conductor has a design critical current of 100 kA at 10 T and 4.5 K and is designed specifically for high-current bus-bars and large detector-type magnets. It therefore features a copper jacket and practical conduction cooling via a cooling line embedded in the jacket.read more
