Diagnostics for steady state plasmas

H-J Hartfuss, R König, A Werner2006年Plasma Physics and Controlled FusionIF 2.2出版社

Problems related to the development of diagnostics for steady state fusion plasma experiments are discussed. The paper concentrates on those necessities already appearing in current non-burning plasma fusion experiments when extending pulse lengths beyond 10 s, i.e. thermal load, erosion, deposition and long-time signal integration in magnetic diagnostics. Problems arising from high power ECRH under conditions of incomplete absorption are outlined. Individual standard diagnostic systems are discussed to identify their specific problems as well as the opportunities connected with long pulse operation. Burning plasma experiments characterized by intense n- and γ-radiation are briefly reviewed for reasons of completeness, dealing with radiation induced processes in windows, fibres, cables and mirrors. Methods of data handling, real time monitoring and plasma control are outlined.

定常状態の核融合プラズマ実験における診断装置の開発に関連する問題について論じる。本論文は、パルス長を10秒超に延長する際に、既存の非燃焼プラズマ実験においてすでに顕在化している必要性、すなわち熱負荷、損耗、および磁気診断における長時間信号積分に焦点を当てる。不完全な吸収条件下での高パワーECRHに起因する問題を概説する。個々の標準診断システムについて、その固有の問題と長時間パルス運転に伴う可能性を特定するために考察する。強い中性子線およびガンマ線放射を特徴とする燃焼プラズマ実験について、窓、光ファイバー、ケーブル、ミラーにおける放射線誘起過程を扱う観点から、完全性を期すために簡潔にレビューする。データ処理、リアルタイム監視、およびプラズマ制御の方法を概説する。
