Statistical analysis of the current-sharing temperature evolution in Nb3Sn cable-in-conduit-conductors for ITER

Pierluigi Bruzzone, Davide Uglietti, Boris Stepanov, Rainer Wesche

During the test of ITER conductors at nominal conditions, a degradation of the current sharing temperature has been observed after electromagnetic cyclic loading. Rather than focusing on the microscopic phenomena at the origin of the degradation, the degra ...

Slip-stick mechanism in training the superconducting magnets in the Large Hadron Collider

Pier Paolo Granieri

Superconducting magnets can exhibit training quenches during successive powering to reaching nominal performance. The slip-stick motion of the conductors is considered to be one of the mechanisms of training. In this paper we present a simple quantitative ...
