M7.3.2: Dipole Nb$_{3}$Sn model magnet finished

This report presents the thermal modelling of the Nb$_{3}$Sn magnet called Fresca2 within the EuCARD-HFM project. The goal of this study is to predict the thermal behaviour of the magnet and to calculate the maximum temperature difference in the magnet structure during steady and transient state conditions. Results of the maximum temperature difference are compared with the temperature margin allowed. The steady state thermal calculations of the magnet are performed with AC losses due to ramp rate and homogeneous dissipation of heat as input heat loads. The transient calculations model the cool-down process. The thermal modelling was performed for several scenarios for steady and unsteady processes and for two base temperatures of 1.9 K and 4.2 K.
