Abstract :
A model coil for the 40-T hybrid magnet is under construction at the High Magnetic Field Laboratory, Chinese Academy of Sciences. The model coil is layer wound with a rectangular Nb3Sn cable-in-conduit conductor and adopts "wind-and-react" manufacturing technology. The model coil will simulate same electromagnetic loads of B × I as the superconducting outsert of the 40-T hybrid magnet in the performance tests. The thermohydraulic behavior of the model coil during various operating scenarios was simulated by the numerical model Gandalf. The charging process and the cyclic operation of the model coil are analyzed in this study. The temperature rise and margin of the conductor due to the ac losses are computed and presented.
