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.
