JT-60 SA托卡马克的建设已于2020年3月如期完成。托卡马克各主要部件的制造和组装均满足技术要求，包括尺寸精度和功能性能。等离子体加热系统和诊断的开发也取得了进展，包括演示了在多个频率下的有利电子回旋频率范围传输，以及实现了高能强负离子束的长期维持。所有托卡马克运行控制系统的开发已经完成，同时改进的等离子体平衡控制方案适用于超导托卡马克，包括ITER。为准备托卡马克操作，等离子体放电方案已建立使用这种先进的平衡控制器。低温系统和电源系统的单独调试证实，这些系统满足设计要求，包括直接有助于热核实验堆的运行方案，如对超导托卡马克动态运行至关重要的低温装置热负荷波动的主动控制。综合调试（IC）通过真空容器和低温恒温器的真空抽吸开始，然后转移到托克马克和线圈激励测试的冷却。对于所有TF、EF和CS线圈，确认了向超导状态的转变。TF线圈电流成功达到25.7 kA，这是TF线圈的标称工作电流。对于2.25 T的标称环向场，施加ECRF并产生ECRF等离子体。然而，由于超导平衡场线圈中的一个的过电流事件和线圈的端子接头处的电压保持能力不足引起的He泄漏，IC被暂停。JT-60 SA在H模和高β稳态等离子体研究中的独特重要性已被先进的集成模型所证实。JT-60 SA的组装、集成电路和等离子体运行经验为降低ITER风险和有效实施ITER运行做出了贡献。
Construction of the JT-60SA tokamak was completed on schedule in March 2020. Manufacture and assembly of all the main tokamak components satisfied technical requirements, including dimensional accuracy and functional performances. Development of the plasma heating systems and diagnostics have also progressed, including the demonstration of the favourable electron cyclotron range of frequency (ECRF) transmission at multiple frequencies and the achievement of long sustainment of a high-energy intense negative ion beam. Development of all the tokamak operation control systems has been completed, together with an improved plasma equilibrium control scheme suitable for superconducting tokamaks including ITER. For preparation of the tokamak operation, plasma discharge scenarios have been established using this advanced equilibrium controller. Individual commissioning of the cryogenic system and the power supply system confirmed that these systems satisfy design requirements including operational schemes contributing directly to ITER, such as active control of heat load fluctuation of the cryoplant, which is essential for dynamic operation in superconducting tokamaks. The integrated commissioning (IC) is started by vacuum pumping of the vacuum vessel and cryostat, and then moved to cool-down of the tokamak and coil excitation tests. Transition to the super-conducting state was confirmed for all the TF, EF and CS coils. The TF coil current successfully reached 25.7 kA, which is the nominal operating current of the TF coil. For this nominal toroidal field of 2.25 T, ECRF was applied and an ECRF plasma was created. The IC was, however, suspended by an incident of over current of one of the superconducting equilibrium field coil and He leakage caused by insufficient voltage holding capability at a terminal joint of the coil. The unique importance of JT-60SA for H-mode and high-β steady-state plasma research has been confirmed using advanced integrated modellings. These experiences of assembly, IC and plasma operation of JT-60SA contribute to ITER risk mitigation and efficient implementation of ITER operation.
