As one of the R&D of ITER. a hydraulic performance of NbAl insert coil was measured and compared with other NbSn conductors. It seems that a longer twist pitch will promote a triangle helium flow space among 4th twist stage cables, jacket and center channel and contribute reduction of pressure drop. Under 500 kN/m of the electromagnetic force, the pressure drop of the NbAl insert decreased by approximately 5%. NbAl conductor indicated quit rigid characteristic under the electromagnetic force and suitable for future magnet with higher magnetic field and current.

The cool down of CS model coil and NbAl insert was started on March 4, 2002. It took almost one month and immediately started coil charge since April 3, 2002. The charge test of NbAl insert and CS model coil was completed on May 2, 2002. All of the experiments including the warm up was also completed on May 30, 2002.In this campaign, total shot numbers were 102 and the size of the data file in the DAS (Data Acquisition System) was about 5.2 GB. This report is a database that consists of the log list and the log sheets of every shot.

Vurrent sharing temperature (Tcs) measurement of ITER toroidal field insert was performed. The coil is NbSn superconducting coil and was installed inside of the ITER CS model coil as a backup field coil. Relation between the voltage of individual strand composing TF insert conductor and the measured voltage using the taps on the jacket is investigated and the evaluation method for Tcs measurement was established. The obtained results shows that there was discrepancy between the expected value from the strand data and the measured value which is lower by about 1.2K. Some discrepancy was already observed just after cool down of the insert before energizing.

JAEA is procuring conductors for ITER Central Solenoid (CS) and has evaluated its superconducting performance using CS Model Coil Test facility. We measured Tcs values during cyclic charge of 16,000 cycles and warm-up and cool-down cycle of 3 times. And we measured effect of coil deformation by electro-magnetic force on Tcs values and performed quench test. In this presentation, test method will be reported.
