Dr. Gerhard Ulm
Gerhard Ulm, born in 1953, studied physics at the University of Würzburg. After graduating, he joined the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, where he established the field of laser spectroscopy on radionuclides generated by heavy ion fusion. He received his doctoral degree on this subject from the University of Mainz in 1984. After that, he became a Fellow at CERN in Geneva, where he worked on various cooperation projects at the mass separator ISOLDE. In November 1986, he joined the Physikalisch-Technische Bundesanstalt (PTB) in Berlin.
At first, he performed his field of work – radiometry with synchrotron radiation – at the electron storage ring BESSY I, after 1999 at BESSY II, and since 2008 additionally at PTB's own storage ring the Metrology Light Source (MLS). In his posts at PTB as the Laboratory Head from 1989 and as the Head of Department from 1995, he extended the metrological use of synchrotron radiation to include the fields of reflectometry, scatterometry and spectrometry. He also developed the entire spectral range from terahertz to hard X-rays for metrology.
Since January 2010 Gerhard Ulm has headed PTB's Division 7 "Temperature and Synchrotron Radiation"; since September 2014 he has been the Head of the Berlin Institute.
