Method for determination of the conductor current sharing temperature using traveling heat slug in the ITER TFMC

During the TFMC (Toroidal Field Model Coil) quench experiment, a part of the pipe supplying helium to the TFMC is heated in order to reach, by forced circulation, the current sharing temperature of the conductor at peak field. During this experiment, the TFMC conductor is supplied with a current of 80 kA and the maximum magnetic field on the tested pancake is around 7.2 T. The aim of this paper is to determine the values of the experimental conditions needed to quench the TFMC conductor before the joint.
