XAFS spectroscopy in a lab: a HAPG von Hamos laboratory spectrometer

2 pm CEST

The investigation of the chemical bond state by measuring the fine structure of absorption edges (XANES, EXAFS) has so far been a domain of synchrotron radiation. In this webinar, Dr. Wolfgang Malzer, a research scientist at the Berlin Laboratory for Innovative X-ray technologies, is presenting a modified Von Hamos laboratory spectrometer, based on pyrolytic graphite crystals and 2D hybrid photon counting detector. This new spectrometer makes it possible to achieve high-energy resolutions and large solid angles of the detection. Results of demonstration experiments and of applications in chemical research are shown. Prospects and possible use cases of laboratory XANES and EXAFS are discussed.
