摘要

利用合肥800 MeV电子存储环同步辐射(HESYR)作为紫外真空紫外光谱辐射测量的绝对标准,标定了传递标准氘灯光源的光谱辐亮度。采用德国国家物理技术研究院(PTB)的数据处理及不确定度分析方法,得到了两支氘灯在115～300nm波段的光谱辐亮度数据,其相对定标不确定度为12.1%。详细分析了相关参量对定标不确定度的贡献,指出辐射计量系统偏振特征量的不确定度贡献最大。在164～300 nm波段,德国德国国家物理技术研究院在BESSYⅡ同步辐射装置上标定的绝对光谱辐亮度值与本实验在中国合肥同步辐射装置上标定的绝对光谱辐亮度值之间一致性优于±20%,在给定的不确定度范围内两光谱辐射标准定标结果一致。

Abstract

The spectral radiance of transfer standard-deuterium lamp is calibrated using Hefei 800 MeV electron storage ring synchrotron radiation (HESYR) as an absolute UV-VUV spectral radiometric standard. The data processing and uncertainty analysis method of PTB is employed, in 115～300 nm the spectral radiance values of two deuterium lamps are obtained, and the overall uncertainty for D2 lamp calibration is 12.1%. A detailed analysis of the contributions to this uncertainty points out that the major part is caused by the uncertainty of the polarization properties of the radiometric instrumentation. In the range of 164～300 nm the D2 lamp absolute spectral radiant distribution obtained using HESYR China and that derived from BESSYⅡGermany have a discrepancy within ±20%. They are consistent within the given uncertainties.
