目前为热核实验堆预见的大多数光学诊断将采用容器内金属反射镜作为等离子体观察部件。反射镜被用来观察非常宽的波长范围内的等离子体辐射：从大约1纳米到几毫米。在恶劣的热核实验堆环境中，反射镜会受到侵蚀、沉积、粒子注入和其他不利影响，这将改变其光学特性，影响各自诊断系统的整体性能。第一面镜子专家工作组是在国际托卡马克物理活动专题小组诊断专题小组下设立的，目的是协调和指导对诊断镜子的调查，以便为热核实验堆诊断系统制定最佳、可靠和耐用的解决方案。本文介绍了在Tore-Supra、Textor、DIII-D、TCV、T-10、TRIAM和LHD上进行的各种ITER候选镜面材料在不同等离子体条件下的测试结果，以及镜面性能和镜面清洗技术的实验室研究概况。将解决目前诊断镜研发中的任务。
The majority of optical diagnostics presently foreseen for ITER will implement in-vessel metallic mirrors as plasma-viewing components. Mirrors are used for the observation of the plasma radiation in a very wide wavelength range: from about 1 nm up to a few mm. In the hostile ITER environment, mirrors are subject to erosion, deposition, particle implantation and other adverse effects which will change their optical properties, affecting the entire performance of the respective diagnostic systems. The Specialists Working Group (SWG) on first mirrors was established under the wings of the International Tokamak Physics Activity (ITPA) Topical Group (TG) on Diagnostics to coordinate and guide the investigations on diagnostic mirrors towards the development of optimal, robust and durable solutions for ITER diagnostic systems. The results of tests of various ITER-candidate mirror materials, performed in Tore-Supra, TEXTOR, DIII-D, TCV, T-10, TRIAM-1M and LHD under various plasma conditions, as well as an overview of laboratory investigations of mirror performance and mirror cleaning techniques are presented in the paper. The current tasks in the R&D of diagnostic mirrors will be addressed.
