The FRESCA2 dipole magnet has been developed within a collaboration between CEA Saclay and CERN. The main goal of the magnet is to provide a 13 T nominal bore field into a clear aperture of 100 mm diameter, for the second generation cable test facility FRESCA2 (Facility for the REception of Superconducting Cables) at CERN. The coils have been produced in a joint effort between CEA Saclay and CERN. A first magnet assembly has been performed at CERN, pre-loaded at room temperature, and cooled-down in liquid helium. A first training campaign has recently been carried out at CERN. The assembly process will be described, then the electromagnetic and mechanical behaviour during the training will be presented.
