Metrology Light Source in Adlershof

The Physikalisch-Technische Bundesanstalt, the national metrology institute of Germany, plays a leading role worldwide in the use of synchrotron radiation for metrology. In Berlin-Adlershof, PTB uses BESSY II and its own "Metrology Light Source" electron storage ring, the latter operated in close cooperation with the HZB, as national standards for radiation in the spectral range from ultraviolet (UV) to hard X-rays. The storage rings as calculable radiation sources are the fundament for the calibration of e.g. energy dispersive X-ray detectors and UV spectrometers for space research. In addition to radiometric applications, PTB's instrumentation offers excellent measurement capabilities, among others, for the characterization of optical components and the materials metrology by chemical and dimensional analysis of thin films and nanostructures. This is the basis for numerous cooperations with international partners from industry and research.
