| Zusammenfassung | The spectral radiant intensity of synchrotron radiation can be accurately calculated by the Schwinger formula, thus making electron storage rings primary sources. This fact 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 the UV and VUV for almost 30 years. Currently, we operate the electron storage rings BESSY II and MLS as primary source standards. The transfer sources are compared to the respective primary source standard by means of a suitable, wavelength-dispersive transfer station at each of the storage rings. The spectral region from 7 nm to 400 nm is covered, which is unique in the world. For the dissemination of this radiometric scale in the short wavelength spectral region, PTB operates transfer sources that are based on a hollow cathode discharge. We report on the status of these VUV transfer sources. |
