EU contribution to the test and analysis of the ITER poloidal field conductor insert and the central solenoid model coil

摘要

The PFCI is a single-layer solenoid wound from a 45 m long ITER-type NbTi dual-channelcable-in-conduit conductor, designed to be representative of the one currently proposed for theITER PFI&6 coils. The PFCI, installed in the bore of the ITER central solenoid model coil(CSMC) at JAEA Naka, Japan, and well instrumented from both the thermal hydraulic and theelectromagnetic points of view, has been successfully tested in June—August 2008. The testconcentrated on DC performance (current sharing temperature and critical currentmeasurements) and AC loss measurements. The results of the analysis of those measurementsare reported in the paper, with particular attention to the comparison with the PFCI shortsample, which was previously tested in the SULTAN facility. The evolution of the DCperformance of the CSMC is also discussed.
