日本原子能机构（JAEA）已经制造和测试了四个导体样品组成的高性能股线的青铜路线工艺制造的ITER中央螺线管（CS）导体。在45.1 K和10.85 T沿着48.8 kA和10.85 T的循环负载下，第一个名为JACS 01的苏丹样品的电流共享温度（Tcs）最初分别为6.0 K和6.1 K，然后在6000次循环后分别为5.3 K和5.5 K。作为名为JACS02的第二个苏丹样品的结果，每个导体的Tcs值最初分别为7.2 K和6.8 K，然后在10000次循环后分别为6.6 K和6.1 K。在测试活动结束时，Tcs降解未饱和。从破坏性观察，在高场区的低横向载荷侧观察到大的弯曲。考虑了索与导管架之间的股线屈曲和滑移累积。
Japan Atomic Energy Agency (JAEA) has fabricated and tested the four conductor samples composed of high performance strands manufactured by the bronze-route process for the ITER Central Solenoid (CS) conductor. The current sharing temperature (Tcs) electrically assessed at 45.1 K and 10.85 T along the cycling loading at 48.8 kA and 10.85 T initially were 6.0 K and 6.1 K, and then 5.3 K and 5.5 K after 6000 cycles for the first SULTAN sample named JACS01, respectively. As results of second SULTAN sample named JACS02, the Tcs values initially were 7.2 K and 6.8 K, and then 6.6 K and 6.1 K after 10000 cycles for each conductor, respectively. The Tcs degradation was not saturated at the end of the test campaign. From the destructive observation, the large bending at the low transverse loading side in the high field zone was observed. The strand buckling and accumulating by slipping between the cable and the jacket are considered.
