DC behaviour of NbTi cable-in-conduit conductors for ITER-FEAT
Using the SULTAN test facility the dc behaviour of 3 sub-size NbTi cable-in-conduit (CIC) conductors has been studied. The dc performance of the cables is compared to the critical currents and the current sharing temperatures expected from the strand data. As a basis for this comparison the critical current of the NbTi strands has been measured in the temperature range of 4.2 to 6.5 K in magnetic fields of up to 7.5 T. The dc performance of the NbTi sub-size conductors has been found to be not significantly affected by cyclic loading. In addition, the index of resistive transition of the cables is close to the values determined for the strands. Taking into consideration the self-field of the conductor, the cable critical current and the current sharing temperature are in agreement with the strand data.
