PTB Laboratory at BESSY II

Since 1999, the Opens internal link in current windowPhysikalisch-Technische Bundesanstalt (PTB), Germany’s national metrology institute, utilizes synchrotron radiation at the storage ring BESSY II in Berlin-Adlershof, continuing the work which started already at the former BESSY I storage ring which has been closed at the end of 1999. The PTB laboratory developed into an European center for metrology with synchrotron radiation, used by collaboration partners worldwide.

The PTB departments Opens internal link in current window7.1 and Opens internal link in current window7.2 operate a laboratory at BESSY II with currently twelve experimental stations. PTB offers metrological services to customers and cooperation partners, from routine calibrations to customized metrological solutions and metrology oriented research.

Since 2008, the measurement capabilities are significantly extended and complemented by the Opens internal link in current windowMetrology Light Source.
