The radiant intensity of synchrotron radiation can be accurately calculated with classical electrodynamics. This primary realization of the spectral radiant intensity has been used by PTB at several electron storage rings which have been optimized to be operated as primary source standards for the calibration of transfer sources in the spectral range of UV and VUV for almost 30 years. The transfer sources are compared to the primary source standard by means of suitable wavelength-dispersive transfer stations.The spectral range covered by deuterium lamps, which represent transfer sources that are easy to handle, is of particular relevance in practice. Here, we report on developments in the realization and preservation of the radiometric scales for spectral radiant intensity and spectral radiance in the wavelength region from 116 nm to 400 nm, based on a set of deuterium reference lamps, over the last few decades. An inside view and recommendations on the operation of the D2 lamps used for the realization of the radiometric scale are presented. The data has been recently compiled to illustrate the chronological behaviour at various wavelengths. Moreover, an overview of the internal and external validation measurements and intercomparisons is given.

“…The EUI flight instrument was calibrated with synchrotron radiation from the Metrology Light Source (MLS) of the Physikalisch-Technische Bundesanstalt (PTB) in Berlin [14] . The OBS unit was mounted inside a dedicated high-vacuum tank on a support bracket fixed on a translation/rotation stage, allowing to scan the channel's FOV.…”

The Extreme Ultraviolet Imager (EUI) instrument for the Solar Orbiter mission will image the solar corona in the extreme ultraviolet (17.1 nm and 30.4 nm) and in the vacuum ultraviolet (121.6 nm) spectral ranges.The development of the EUI instrument has been successfully completed with the optical alignment of its three channels' telescope, the thermal and mechanical environmental verification, the electrical and software validations, and an end-toend on-ground calibration of the two-units' flight instrument at the operating wavelengths.The instrument has been delivered and installed on the Solar Orbiter spacecraft, which is now undergoing all preparatory activities before launch.

“…Since 1995, a normal incidence monochromator beamline [2] provided radiation with high spectral purity, and was used for different metrology applications, e.g. detector characterization and calibration, measurement of optical properties of materials and coatings, and also for complete spectrometer characterization in particular for instrumentation intended to be used in space applications [3]. Since 2008, this beamline was located at the Metrology Light Source (MLS) of PTB in Berlin-Adlershof.…”

At the Metrology Light Source, a 630 MeV electron storage ring for the use of synchrotron radiation for metrology applications, a new beamline is dedicated to radiometry in the vacuum-ultraviolet spectral range. The emphasis lies on the traceability of measurements and profound uncertainty analysis. To replace the previously existing normal incidence monochromator beamline which serviced for more than 20 years now at different facilities, a newly designed 2 m off-plane Eagle monochromator beamline concept was developed. Different reflective coatings for mirrors and gratings in combination with order-sorting filters ensure highest spectral purity of the monochromatized radiation in combination with optimized photon flux characteristics. The beamline is planned to go into full operation in late 2022.
