A dedicated low-energy storage ring for metrology with synchrotron radiation
The Physikalisch-Technische Bundesanstalt (PTB), Germany’s national metrology institute, is using synchrotron radiation for metrology and related applications for research and industry. In this context, PTB has extended its activities with an own storage ring, the Metrology Light Source (MLS), designed and built to meet dedicated demands for metrology. The MLS is located in the vicinity of the BESSY II storage ring facility in Berlin-Adlershof (Germany) and started user operation in spring 2008. The PTB departments 7.1 and 7.2 operate a laboratory at the MLS with currently six experimental stations. There, PTB offers capabilities for precision measurements and calibrations in the spectral range from the far infrared / THz to the extreme ultraviolet (EUV), thus complementing the activities of PTB at BESSY II, which cover the short-wavelength spectral ranges from the UV to the X-ray range. At both facilities, PTB offers metrological services to customers and cooperation partners, from routine calibrations to customized metrological solutions and metrology oriented research.
