Abstract
The results on research of the recent design Nb3Sn bronze strand with increased critical current capacity are presented. The strand has been designed and fabricated for use in full scale ITER TF conductor sample for testing in the SULTAN facility. The verification and qualification of strands have been done. The critical current measurements as a function of temperature in the range from 4.2 K to 15 K in magnetic fields up to 12 T have been performed. The results of testing of current sharing temperature Tcs of strand are discussed. The cable in conduit conductor was manufactured in accordance with ITER recommended scheme option 2. The cable design, thickness of wraps of subcable, void fraction and other characteristics of conductor for TF coil have been investigated to produce sample for testing in the SULTAN facility.
