Klaus Attenkofer

Program Manager of Hard X-ray Spectroscopy


Most of my carrier I was working at storage ring based x-ray sources, developing and running programs in the field of materials, chemical, and environmental sciences, with a strong focus on energy sciences. My interest was and is to find new ways, how basic sciences can contribute to the large challenges of applied sciences and forefront engineering. The tools used are the development of new detection concepts, the development of new detection systems and optimized data acquisition systems, the optimization of x-ray optics and sources, and most importantly, the implementation of appropriate sample environments which allow to probe the sample under relevant conditions.

Responsible for Hard X-ray spectroscopy program of NSLS-II: Currently we serve our user community at SSRL at BL2.2 and we build ISS, a damping wiggler beamline focused on high throughput in-situ and operando experiments, QAS a bending magnet beamline focused on QEXAFS in combination with powder diffraction, and TES a tender x-ray beamline which combines spectroscopy and microscopy in the energy range from 1.8KeV to 8KeV. All three beamlines will be operational in 2016.
