建立了高精度光谱辐射计量系统
给出了164~300nm波长间3个光谱辐射标准氘灯光源的比对结果.其中3个光谱辐射标准氘灯光源分别以德国国家物理技术研究院(PTB)BESSYⅡ同步辐射、英国国家物理实验室(NPL)Daresburg同步辐射、中国合肥(国家同步辐射实验室)同步辐射为标准标定.实验中采用相互交替的比对顺序、微机控制比对时间以及抛光氘灯端窗等方法有效的消除了系统误差.实验数据分析结果表明:3个光谱辐射标准氘灯光源的相对光谱分布
在各自给定的不确定度范围内相一致
这也间接的验证了各国建立的紫外 真空紫外辐射标准的一致性.实验中比对引进的误差为1.7%.同时也研究了氘灯的光谱辐射特性.
A high precision spectroradiometric system was established
and the comparisons between three spectral radiant standard sources-deuterium lamps in the range of 164~300nm were given. The three transfer standard deuterium lamps are calibrated based on: BESSYⅡ Synchrotron Radiation of German National Institute of Science and Technology for Metrology(PTB)
Daresburg Synchrotron Radiation of National Physical Laboratory(NPL)in UK
and Synchrotron radiation of HeFei National Laboratory of Synchrotron Radiation in China
respectively as primary standard sources. A series of methods
such as alternative sequence of comparison
computer controlled time consuming
and polishing the window of the deuterium lamp
was adopted to eliminate the systemic error efficiently. And the experimental result data were analyzed. It shows that the relative spectral radiant distributions of the lamps are consistent within the uncertainties designated respectively. It also shows that the consistency between UV-VUV radiometric standards established by different countries is confirmed. The error arising from the comparison is estimated at 1.7%. Meanwhile the spectral radiation characteristics of deuterium lamps are demonstrated.
