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

Pierluigi Bruzzone, Rainer Wesche, Boris Stepanov, Davide Uglietti

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 ...

Computations of AC loss in the ITER magnets, during fast field transients

Jonathan Bryan Lister, Pierluigi Bruzzone

The calculation of AC loss due to the control currents in ITER is a cumbersome task. The reason is that control transients require small field changes (0.1 T or less) at moderate frequency (up to 10 Hz), where effects of partial penetration of the filament ...

T-cs degradation of ITER TF samples due to fast current discharges

Pierluigi Bruzzone, Boris Stepanov, Kamil Sedlák

Direct current tests performed in the past on the conductor samples of the toroidal field (TF) ITER coils revealed degradation of current sharing temperature, T-cs. The degradation progresses with repetitive electromagnetic loading, and also with thermal c ...

Measurements of AC Loss Evolution in ITER TF Conductors

Pierluigi Bruzzone, Kamil Sedlák

AC loss in the Nb3Sn cable-in-conduit conductors (CICC) usually decreases after the conductor undergoes electromagnetic cycling. This can be attributed to the increase of inter-strand resistance due to the detachment of the strand-bonding during cyclic loa ...
