Abstract :
This paper describes the numerical analysis, carried out with the THELMA code, of an ITER-type superconducting cable-in-conduit termination test made by the Paul Sherrer Institute with the JORDI device. In the test, a set of inter-strand and termination-strand resistances was measured, which have been used here to trim the model parameters and to evaluate the model accuracy. A statistical approach is proposed to enhance the accuracy of the results in the presence of random test parameters such as the cable bundles angular initial positions.
