JT-60 Super Advanced (JT-60SA) 的中央电磁阀 (CS) 的多个组件是新开发和测试的。电阻约为2nΩ的对接型接头是为了增加绕组直径而开发的。由玻璃/聚酰亚胺/玻璃胶带和双酚A二缩水甘油醚（DGEBA）环氧树脂组成的绝缘系统在100 kGy的辐照后表现出足够的拉伸强度。 4×4绕组叠层样品经705 kN 36 000次压缩后的绝缘特性能够承受大于21 kV的电压。对超导CS模型线圈进行了热处理和转印。平顶时煎饼温度保持在923+/-4K。煎饼内最大温差为30K。所有制造工艺均已确认，CS将于2013年开始量产。
Several components for central solenoid (CS) of JT-60 Super Advanced (JT-60SA) were newly developed and tested. The butt-type joint, the electrical resistance of which is about 2 n Omega, was developed to increase the winding diameter. The insulation system, which consists of Glass/Kapton/Glass tape and Bisphenol A diglycidyl ether (DGEBA) epoxy, showed sufficient tensile strength after the irradiation of 100 kGy. Insulation characteristics of 4 x 4 winding stack sample after the compression of 705 kN 36 000 times was able to withstand voltages larger than 21 kV. The heat treatment and transfer of the CS model coil with superconductor were conducted. The pancake temperature during flat top was maintained at 923 +/- 4 K. The maximum temperature difference in the pancake was 30 K. All manufacturing processes were confirmed so that the mass production of CS will be started in 2013.
