摘要
叙述了中国科学技术大学国家同步辐射实验室800 MeV电子储存环同步辐射的特性及作为光谱辐射亮度基准的原理和方法,精确计算出同步辐射光源光谱功率空间分布,并在计量学上将同步辐射“经典”理论与标定氘灯光谱辐射亮度结合起来,对“同步辐射作为标准源进行光谱辐射功率计量”进行深入的研究。介绍了国家同步辐射实验室计量光束线站的装置,该装置利用同步辐射波长范围宽、亮度高、辐射特性可精确计算等特点,可用于标定传递标准氘灯的光谱辐射亮度(115~350 nm),并进行了不确定度分析。并与德国技术物理研究院(PTB)标定的氘灯光谱辐射亮度进行比较,两者符合。
Abstract
The characteristics of the 800 MeV electron storage ring of National Synchrotron Radiation Laboratory (NSRL, located in University of Science and Technology of China) are introduced. The theory and the method used to build spectral radiance standard with the synchrotron radiation are presented, and the spatial spectral power distribution of the synchrotron radiation source is calculated accurately. The classical theory of the synchrotron radiation and the spectral radiance luminance calibration of the deuterium lamp are related, and the spectral radiance power metrology using the synchrotron radiation as the standard source is studied extensively. The metrological beamline of NSRL with wide wave range, high luminance and accurately calculated radiance properties is presented, which can be used to calibrate the spectral radiance luminance of the deuterium lamp (1115~350 nm), and the uncertainty is analyzed. The calibration result is consistent with that of physical research institute (PTB) of Deutschland.
