Nb3Sn RRP Strand and Rutherford Cable Development for a 15 T Dipole Demonstrator

Keystoned Rutherford cables made of 28 strands and with a stainless steel core were developed and manufactured using 1-mm Nb
₃
Sn composite wires produced by Oxford Superconducting Technology with 127 and 169 restacks using the Restacked-Rod-Process. The performance and properties of these cables were studied to evaluate possible candidates for 15-T accelerator magnets.
