In the framework of the international collaboration among SIN-Villigen (CH), ECN-Petten (NL) and CNEN-Frascati (I) aiming to the realization of the SULTAN test facility (SUpraLeitender TestANlage) whose general layout has been already described [1] , the CNEN contribution is concerned with the realization of the outer part of the solenoid, i.e. the section which will provide the 6T field in the useful region, the remaining 2T being supplied by the coaxial ECN insert. In the present paper a detailed description of the 6T superconducting solenoid is presented. The main features are: i) pancake structure wound by a Nb-Ti multifilamentary hollow cable ii) cooling by forced flow of slightly subcooled liquid helium. Details of the design, winding technique and structure, the hydraulic circuitry, as well as the status report of the construction will be given and discussed.
