The challenges of a large-scale mirror design for the in-vessel collection system of ITER divertor Thomson scattering (DTS) are under consideration. These are the mirrors located out-of-line vision of fusion plasma (so called 'second mirrors') with a high-reflective Ag-based coating. The paper outlines: approaches providing optical surface shape and angular position stability; Ag coating applicability for ITER in-vessel environment, including resistance to accidental steam ingress. The proposed solutions may also appear to be of some use in other ITER diagnostics and in diagnostics of other fusion devices.

大規模なミラー設計の課題、すなわちITERダイバータ・トムソン散乱(DTS)の炉内集光系における課題について検討している。これらは、核融合プラズマの視線外に配置されるミラー(いわゆる「セカンドミラー」)であり、高反射率のAg系コーティングを施したものである。本論文では、光学面形状と角度位置の安定性を確保するアプローチ、ならびにITER炉内環境におけるAgコーティングの適合性(偶発的な蒸気侵入への耐性を含む)について概説する。提案された解決策は、他のITER計測装置や他の核融合装置の計測装置にも応用できる可能性がある。
