美国国家标准与技术研究所（NIST）通过提供从2 nm到400 nm光谱范围内的校准服务，为不断增长的紫外线用户群体提供服务。在本文中，我们描述了远紫外传输标准探测器程序，美国宇航局支持的光谱仪校准光束线在同步辐射紫外辐射设施，SURF III，和最近升级的SURF电子储存环。NIST发布了几种类型的转移标准探测器，光谱范围从5 nm到254 nm; Al 2 O3无窗光电发射器件，带有集成MgF 2窗口的CsTe光电发射器件，以及抗辐射的单晶硅光电二极管。光谱仪校准光束线使用SURF III的阴极未色散同步辐射作为2 nm至400 nm光谱辐照度的标准。SURF的升级大大提高了基于SURF的校准的准确性，并将有用的光谱范围扩展到更短的波长。总的来说，SURF III的转移标准探测器计划和校准光束线为在远紫外光谱区工作的科学家和工程师提供了独特的校准资源。
The National Institute of Standards and Technology (NIST) serves the growing ultraviolet user community by providing calibration services throughout the spectral range from 2 nm to 400 nm. In this paper we describe the far ultraviolet transfer standard detector program, the NASA-supported Spectrometer Calibration Beamline at the Synchrotron Ultraviolet Radiation Facility, SURF III, and the recent upgrade of the SURF electron storage ring. Several types of transfer standard detectors are issued by NIST in the spectral range from 5 nm to 254 nm; Al2O3 windowless photoemissive devices, CsTe photoemissive devices with integrated MgF2 windows, and radiation-hardened, semiconductive Si photodiodes. The Spectrometer Calibration Beamline makes use of the cathode, undispersed synchrotron radiation from SURF III as a standard of spectral irradiance from 2 nm to 400 nm. The upgrade of SURF has greatly improved the accuracy of calibrations based on SURF, as well as extending the useful spectral range to shorter wavelengths. Taken together, the transfer standard detector program and the calibration beamline at SURF III offer a unique calibration resource for scientists and engineers working in the far ultraviolet spectral region.
