Abstract The paper describes the main experimental results of testing the method of thermographic measurements on a test bench with a plasma-beam facility. The developed method is intended to improve the accuracy of surface temperature measurements of candidate materials of the first wall of future thermonuclear reactors during investigations on the KTM tokamak. The method is based on the use of an external infrared radiation to directly determine the changes in the body reflectivity and a corresponding increase in the accuracy of the temperature measurement by a thermographic camera by recalculating and correcting the value of the emissivity. Resulting curves of changes in reflectivity (emissivity) obtained from the measurements are close to the real values within the inaccuracy of the method. The results of the test demonstrated the efficiency of the proposed method.

在 КTM Tokamak 上进行等离子壁相互作用研究的主动热成像方法的测试结果

摘要 本文描述了在带有等离子束设备的测试台上测试热成像测量方法的主要实验结果。开发的方法旨在提高未来热核反应堆第一壁候选材料在 KTM 托卡马克研究期间表面温度测量的准确性。该方法基于使用外部红外辐射直接确定人体反射率的变化，并通过重新计算和校正发射率值，热像仪测量温度的准确性相应提高。从测量获得的反射率（发射率）变化的结果曲线接近于该方法不准确范围内的真实值。
