Times Cited Count:13 Percentile:65.83(Nuclear Science & Technology)A large tokamak fusion device JT-60 is expected to explore more advanced tokamak discharge scenario towards the ITER and a future power reactor. We believe the following experimental issues are expected to be solved in JT-60. To clarify how to keep a steady-state plasma with high performance, and how to avoid plasma instabilities almost completely. By stimulus of this motivation, several essential development and modifications of plasma control and data acquisition systems have been performed in JT-60. In this report, we discuss the developments to improve the JT-60 plasma control and data acquisition systems. In addition, a future plasma control and data acquisition systems leading to a standard design for a power reactor is envisaged on the basis of the 20-year plasma operation experiences.

Since tokamak magnetic fusion research has just made a step forward to an international collaborative project ITER, the existing tokamaks including JT-60 are expected to explore more advanced operation scenarios toward the ITER and a future power reactor. Hence, we believe the following experimental issues are to be adequately discussed, and possibly to be solved in JT-60: To clarify how to keep a steady-state plasma with high performance, and how to avoid plasma instabilities almost completely. By stimulus of this motivation, the JT-60 plasma real-time control system has been drastically improved with remodeling in hardware as well as in software. In particular, several essential developments for exploring advanced scenarios have been accomplished or are being conducted. In the developments, we adopted the fast board computers' network linking through large reflective memories. Finally, in addition to presentation on plasma control engineering activities in JT-60, we would like to envisage a future plasma control system toward a power reactor.
