Abstract
Selected experimental test results and evaluations are presented for the Japanese Large Coil Task (LCT) test coil used in the International Fusion Superconducting Magnet Test Facility (IFSMTF). Pulsed-field tests, and extended-condition tests in which the coil was operated above the design point (10220 A and 8 T) were performed at the bath temperature of 4.3-4.4 K. In the pulsed field tests, the coil demonstrated a stable operation in the pulsed field of 0.14 T/s and an accompanied overturning force. The AC losses of the coil were measured to be 15 W at the design point, and good agreement was obtained between measurement and calculation. In extended-condition tests, the coil was charged singly to 14 kA (138% of the design current) and obtained 8.8 T, where the coil had a quench. In the full torus, the coil demonstrated a stable operation at 11 kA (107%) and 9.0 T, and in a final operation, the coil reached 9.1 T at 10.8 kA (106%) without a quench.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
