A wide bore superconducting solenoid is the core of the NAFASSY (NAtional FAcility for Superconducting SYstems) test facility, which is under construction at the University of Salerno. The NAFASSY laboratory is a joint program among University of Salerno, ENEA, CRdC and INFN under the financial support of the Italian Ministry for University and Research. The facility, hosted in a new building, includes a 250 W supercritical He refrigerator, a 20kA two quadrants (-20V, +25V) power converter for feeding the solenoid or INFN fast ramped accelerator magnets, and a 50kA/+12V power supply for the testing sample. The completion and the commissioning of the facility is foreseen within 2016. The NAFASSY magnet is a large-bore Nb3Sn solenoid, able to provide a peak field of 8 T close to the insert inner radius. Having a warm bore diameter of 1144 mm and a height of 1276 mm, the solenoid will allow to perform tests relevant for long size NbTi or medium-field Nb3Sn Cable-In-Conduit Conductors (CICCs), as well as small magnets, at variable temperature (ranging from 4.2 K to 10 K) in the presence of a transverse magnetic field. In fact, the warm bore makes the sample under test to be independent of the background solenoid. The design of the magnet is based on a rectangular CICC, cooled by forced flow supercritical He at 4.5 K and fed at a maximum current of 20 kA through a pair of high temperature superconductors current leads. The detailed design of the 8T solenoid, including the electro-magnetic, structural and thermo-hydraulic analysis, will be reported, as well as the production status.
