“…Samples were driven with currents going from 0 to 68 kA repeatedly, and at specified cycles ( , 200, 400, 600, 800, and 1000), a run was performed. The early voltages and/or the voltage slopes [9] are small enough to ignore the linear correction described in [4]. The offsets of all voltage tap arrays of each leg were within 1 at 68 kA.…”

Two identical conductor samples were fabricated from 110 m length cable prepared for qualification of the manufacturing process for Phase II procurement of ITER TF conductor. Superconducting strand characteristics, cabling specifications, and the stainless steel jacket sections are described. Sample assembly and instrumentation of various voltage taps and temperature sensors have been prepared according to specified procedures for conductor performance qualification. The performance test program which was agreed to by the SULTAN working group was applied to the conductor samples. To assess the current sharing temperature , standard analysis procedures were adopted. The of both samples at 68 kA with a background field of 10.78 T after a 1000 cyclic load are well above the acceptance criteria. Behavior of individual "star" voltage taps which are located at different positions and which are possible origins of rather large discrepancies in the of identical samples is discussed. The effective strain and the transition index of the samples are obtained from the experimental data.

“…The other three samples (JATF1, JATF3 and USTF1) were delivered to CRPP ready for test in SUL-TAN. The instrumentation of the samples evolved to very high level of complexity [16]. Two samples (TFPRO2 and JATF2) were tested twice, with enhanced instrumentation in the second campaign.…”
