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. The magnet has been assembled at CERN, pre-loaded at room temperature, cooled-down in liquid helium, and powered with several current cycles. The magnet is mechanically instrumented with strain gauges on the external shell, tie rods, and central post of the coils. This paper reports the results of the mechanical measurements collected during pre-load, cool-down, powering, and warm-up of the magnet. This data is also compared with a 3D mechanical model, in order to validate different assumptions such as friction coefficients, material properties, and pre-stress levels.
