Metrology Light Source

A dedicated low-energy storage ring for metrology with synchrotron radiation

The Opens internal link in current windowPhysikalisch-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 Opens external link in new windowBESSY II storage ring facility in Opens external link in new windowBerlin-Adlershof (Germany) and started user operation in spring 2008. The PTB departments Opens internal link in current window7.1 and Opens internal link in current window7.2 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 Opens internal link in current windowPTB 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.
