Most of the ITER optical diagnostics aiming at viewing and monitoring plasma facing components will use in-vessel metallic mirrors. These mirrors will be exposed to a severe plasma environment and lead to an important tradeoff on their design and manufacturing. As a consequence, investigations are carried out on diagnostic mirrors toward the development of optimal and reliable solutions. The goals are to assess the manufacturing feasibility of the mirror coatings, evaluate the manufacturing capability and associated performances for the mirrors cooling and polishing, and finally determine the costs and delivery time of the first prototypes with a diameter of 200 and 500 mm. Three kinds of ITER candidate mock-ups are being designed and manufactured: rhodium films on stainless steel substrate, molybdenum on TZM substrate, and silver films on stainless steel substrate. The status of the project is presented in this paper.
国际热核聚变实验堆（ITER）的大多数旨在观察和监测面向等离子体部件的光学诊断设备将使用安装在真空室内的金属镜。这些镜子将暴露在恶劣的等离子体环境中，这导致在其设计和制造方面需要进行重要的权衡。因此，正在对诊断镜展开研究，以开发出最佳且可靠的解决方案。目标是评估镜面涂层的制造可行性，评估镜子冷却和抛光的制造能力及相关性能，最终确定直径为200毫米和500毫米的首批原型的成本和交付时间。正在设计和制造三种ITER候选模型：不锈钢基底上的铑膜、TZM基底上的钼以及不锈钢基底上的银膜。本文介绍了该项目的进展情况。
