Abstract

The upgrading of the SULTAN test facility requires the design and the construction of a set of three insert coils, one for each SULTAN partner, able to reach a field of 12 T in a 58 cm inner bore. The ENEA is engaged in the realization of one of these coils and this paper deals with the superconducting properties of the Nb-1Al base wire which will be used for the composite cable of the ENEA insert coil. The wire made by 55 filaments of Nb-3Al intermetallic compound is based on a fabrication technology developed several years ago and whose results have been reported elsewhere. Those conductors, however, were not designed for a particular magnet, so that when we started the design of the 12 T insert coil strong modifications in the whole fabrication process have been necessary in order to meet the specifications for this magnet. The present deals with a conductor developed "ad hoc" for the SULTAN insert coil and results concerning critical current density in the high field and ultimate size of filaments are reported.
