Abstract
Options for implementing the IR thermography diagnostic system in a TRT facility are considered. Two variants of the optical scheme for measuring the temperature of the first wall and divertor targets are proposed: a wide-angle system combined with two divertor channels and a four-channel viewing system. The optical resolution of both systems and the levels of the collected signal are numerically simulated. On the basis of the calculations performed, conclusions are drawn about the compliance of the systems with the requirements for measuring the temperature of TRT plasma-facing elements. The sources of the temperature measurement error are considered, and the error caused by the reflection of radiation from structural plasma-facing elements by the surface under study is estimated. Calibration issues for IR thermography diagnostics are also discussed.
摘要 考虑了在 TRT 设备中实施红外热成像诊断系统的各种选择。提出了测量第一壁和分流目标温度的两种光学方案：一种是与两个分流通道相结合的广角系统，另一种是四通道观察系统。对这两种系统的光学分辨率和所收集信号的电平进行了数值模拟。在计算的基础上，得出了系统是否符合测量 TRT 等离子体面元件温度要求的结论。考虑了温度测量误差的来源，并估算了所研究表面对面向等离子体的结构元件的辐射反射造成的误差。还讨论了红外热成像诊断的校准问题。
