X-ray Spectrometry

Working Group 7.24

Profile

The X-ray spectrometry group provides services, research and development for x-ray spectroscopic measurement techniques using synchrotron radiation. The developed experimental methods as well as the highly specialized and calibrated instrumentation allows for reference-free quantitative experiments and supplements available commercial laboratory equipment.

The group operates three beam lines at the PTB laboratory at the BESSY II, covering a photon energy range from 78 eV to 60 keV (15.9 nm to 0.02 nm).

Research activities and expertise cover the fields of surface and interface characterization of nano- and micro-scaled samples from key technologies, e.g. nanoelectronics, biotechnology, energy conversion and storage or medicine exists.
