The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of matter and materials, energy and environment and human health. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether PSI employs 2100 people.

For the Coherent X-Ray scattering Group we are looking for a

Postdoctoral Fellow
Correlative nanostructure analysis using small-angle X-Ray scattering (SAXS) tomography and ptychographic nanotomography
Your tasks

The project aims at the application of nanostructure characterization using SAXS tensor tomography (SASTT) and ptychographic nanotomography (PXCT) to a fuel cell cathode material. It is a collaboration between Chalmers University of Technology (Goteborg, Sweden), Paul Scherrer Institut (Villigen, Switzerland), and MAX IV (Lund, Sweden). Your tasks will be:

  • Algorithm and experimental method development in SAXS imaging in 2D and 3D
  • Experiments will be performed at the cSAXS beamline in SLS and, as instrumentation becomes available, in MAX IV
  • Knowledge transfer from PSI to MAXIV for scanning SAXS experiments
  • Presentation of results at conferences, workshops and in peer-reviewed scientific journals
  • User support at the cSAXS beamline
Your profile
  • PhD degree in physics or similar natural science discipline, signal/image processing or engineering
  • Experience in experimental data acquisition and/or analysis
We offer

Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure.
