Abstract

The ITER superconducting magnet system consists, besides six poloidal field coils and the central solenoid, of 18 toroidal field coils with the size of 16.6 m x 9 m and a weight of 400 t each. For each of these TF coils an intensive cold test is recommended prior to the installation into the torus in order to minimize the risk of malfunction which would cause tremendous costs and massive time delay. This paper presents the testing possibilities and a preliminary design of such a cold test facility including the process engineering of a cooling system.
