| Abstract | The Roebel concept allows for the cabling of high Jc YBa 2Cu3O7-δ CC tapes which are commercially available in reasonable lengths. This approach to cable design leads to several technological improvements for the manufacture of the next generation of high field magnets. For instance, a reduction in inductance is a key point for the protection of HTS[?] coils generating fields in the range of 40-50 T, such as those needed for the last stage of the cooling channel of a Muon Collider. Here we describe the measurement of the current density uniformity of YBCO[?] coated conductors at 77 K, the manufacture of Roebel cables from these coated conductors at IRL and the measurement of the critical current of the assembled cable in liquid nitrogen. The results compare favorably to the Jc of single tapes, permitting an estimation of the cable Ic at 4.2 K. © 2011 IEEE. |
