紫外-真空紫外光谱辐射计量线站

近年来，随着空间科学、天体物理学、受控核聚变、等离子体物理和紫外激光研究的发展，迫切地需要把光谱辐射标准由红外—可见一近紫外延伸至真空紫外乃至软X射线波段。同步辐射不仅可作为紫外、可见、红外波段光谱辐射光源，同时还可作为真空紫外和软X射线波段的标准光源，为各种辐射光源和探测器进行光谱辐射标定。在我国的国家同步辐射实验室二期工程中正在建设的光谱辐射标准及计量测试线站，它包括两条光束线和三个实验站，本文重点描述在110—400nm的紫外和真空紫外光谱范围建设的光源辐射标准及传递标准专用线站。

Beamline and station of radiometry in the UV-VUV spectral regions

Over the last few years, along with the developments of space science, astrophysics, controlled nuclear fusion, plasma physics and ultraviolet laser research, the need is urgent for the radiometric standards from the infrared, the visible and the near ultraviolet spectral ranges expanding to the ultraviolet, the vacuum ultraviolet and the soft X -ray spectral ranges. Not only can synchrotron radiation (SR) be used as spectral radiation standard source in the ultraviolet, the visible and the infrared spectral ranges, but also it can be used as primary source standard in the vacuum ultraviolet and the soft X-ray spectral ranges. SR can calibrate spectral radiation for various radiation sources and the detectors. The Spectral Radiation Standard and Metrology beam-lines and experimental stations in the NSRL Phase II Project are under construction that include two beam-lines and three experimental stations. This paper describes the dedicated facility for light source of primary standard and transfer standard in the UV and VUV spectral ranges from 110 to 400nm.
