Abstract

Roebel cables made from REBCO coated conductors meet the requirements of accelerator magnets for high-current carrying capability, compactness and transposition. Previous work evidenced that the transverse stress distribution and the electrical protection of the first generation Roebel cables measured at CERN had to be improved. New Roebel cables incorporating copper stabilizer have been designed, produced at KIT and extensively characterized at CERN at 4.2 K and in external fields of up to 9.6 T. In this paper, we report on the optimisation of the cable design and on the results of the electrical and mechanical measurements performed at CERN on a new generation of cables.
