The present paper is devoted to a first assessment of the DEMO diagnostics systems and controls in the context of pulsed and steady state reactor design under study in Europe. In particular, the main arguments treated are: (i) The quantities to be measured in DEMO and the requirements for the measurements; (ii) the present capability of the diagnostic and control technology, determining the most urgent gaps, and (iii) the program and strategy of the research and development (R&D) needed to fill the gaps. Burn control, magnetohydrodynamic stability, and basic machine protection require improvements to the ITER technology, and moderated efforts in R&D can be dedicated to infrared diagnostics (reflectometry, electron cyclotron emission, polarimetry) and neutron diagnostics. Metallic Hall sensors appear to be a promising candidate for magnetic measurements in the high neutron fluence and long/steady state discharges of DEMO.

本論文は、欧州で研究中のパルス運転および定常状態炉設計の文脈におけるDEMO診断システムと制御の最初の評価に充てられている。特に、扱われる主要な論点は以下の通りである:(i) DEMOで測定すべき量と測定に対する要件;(ii) 診断・制御技術の現有能力と、最も緊急のギャップの特定;(iii) そのギャップを埋めるために必要な研究開発(R&D)のプログラムと戦略。燃焼制御、磁気流体力学安定性、および基本的な機器保護にはITER技術からの改善が必要であり、赤外線診断(反射測定、電子サイクロトロン放射、偏光測定)および中性子診断には適度なR&D努力を充てることができる。金属製ホールセンサーは、DEMOの高い中性子フルエンスおよび長時間/定常状態放電における磁気測定の有望な候補であると思われる。
