托克马克冷屏表面超低温发射率实验研究

Experimental study on silver plating surface emissivity of the superconducting Tokamak thermal shield at super-low temperature

采用基于傅里叶红外光谱仪的材料红外光谱发射率测试装置,对全超导托克马克装置冷屏镀银表面进行超低温(80K)发射率实验研究,得到不同镀银表面从常温到超低温条件下的表面发射率,为冷屏表面处理工艺方法提供了依据。

In this paper, the silver plating surface emissivity of the superconducting Tokamak thermal shield at superlow temperature was studied based on the Fourier infrared spectrometer. Through the experiment the emissivity coefficient was a- chieved. The results will provide scientific basis for the surface treatment process of the thermal shield.
