This paper reports on a 17 Tesla superconducting magnet fabricated and tested. The designed field is 17 T with 160 A in the 33 mm bore at 4.2 K. The magnet is composed of two sets of Nb{sub 3}Sn coils and a NbTi coil graded into two sections. The Nb{sub 3}Sn conductor is a Ti added Nb tube processed conductor, reacted after coil winding. The conductor reaction process was developed to get 880 A/mm{sup 2} current density without matrix under 14.5 T and residual resistivity ratio (RRR) 87. The stabilization method applied to the coil was a flexibly supported epoxy resin impregnated coil without a mandrel.
