The JT-60SA device has been designed as a highly shaped large superconducting tokamak with variety of plasma actuators (heating, current drive, momentum input, stability control coils, RMP coils, W-shaped divertor, fuelling, pumping etc) in order to satisfy the central research needs for ITER and DEMO. In the ITER- and DEMO-relevant plasma parameter regimes and with the DEMO-equivalent plasma shapes, JT-60SA quantifies the operation limits, plasma responses and operational margins in terms of MHD stability, plasma transport and confinement, high energy particle behaviors, pedestal structures, SOL and divertor characteristics. By integrating advanced studies in these research fields, the project proceeds "simultaneous and steady-state sustainment of the key performances required for DEMO" with integrated control scenario development applicable to the highly self-regulating burning high beta high bootstrap current fraction plasmas.
