The JT-60SA device has been designed as a highly shaped large superconducting tokamak with a variety of plasma actuators (heating, current drive, momentum input, stability control coils, resonant magnetic perturbation 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 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 behaviour, pedestal structures, scrape-off layer 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-β high bootstrap current fraction plasmas.

JT-60SA装置は、ITERおよびDEMOの中心的な研究ニーズを満たすために、多様なプラズマアクチュエータ(加熱、電流駆動、運動量入力、安定性制御コイル、共鳴磁場摂動コイル、W型ダイバータ、燃料供給、排気など)を備えた、高度に成形された大型超伝導トカマクとして設計されてきた。ITERおよびDEMOに関連するプラズマパラメータ領域において、DEMOと等価なプラズマ形状を用いて、JT-60SAは、MHD安定性、プラズマ輸送と閉じ込め、高エネルギー粒子挙動、ペデスタル構造、スクレイプオフ層およびダイバータ特性の観点から、運転限界、プラズマ応答および運転余裕を定量化する。これらの研究分野における先進的研究を統合することにより、プロジェクトは、高度に自己制御的な燃焼高β・高ブートストラップ電流分率プラズマに適用可能な統合制御シナリオ開発とともに、「DEMOに要求される主要性能の同時かつ定常的な維持」を進める。
