Enlightening Science
European XFEL is an international non-profit company located in the Hamburg area in Germany. It operates a 3.4 km-long X-ray laser, which produces X-rays of unique quality for studies in physics, chemistry, the life sciences, materials research and other disciplines. The diverse scientific facilities at European XFEL enable scientists from across the globe to carry out a wide range of experimental techniques.

For our EXPLODE group we are looking for a

Postdoctoral scientist - Resonant X-Ray Spectroscopy for Fusion Science (f/m/d)

The Position
This postdoctoral scientist is funded by the BMFTR as part of the "EXPLODE" (Experimental X-ray Platforms for Optimisation and Diagnosis of inertial fusion Energy) research group, and is focused on developing resonant X-Ray scattering and spectroscopy diagnostics for fusion science on XFELs.
The BMFTR Project code is 13F1044 for the project "Experimentelle Röntgenplattformen zur Optimierung und Diagnose der Trägheitsfusion" (EXPLODE).
  • Develop resonant X-Ray spectroscopy methods for high-temperature, high-density and fusion-relevant experimental platforms on XFEL experiments
  • Develop and apply analysis and modelling approaches for resonant inelastic x-ray scattering
  • Work to define experimental requirements, targetry, and spectroscopic diagnostics to measure the properties of transient plasma states
  • Plan, coordinate, and participate in experiments at European XFEL and international facilities
  • Disseminate results through publications, conferences and collaborations
Requirements
  • PhD in Physics, Materials Science, Chemistry, Engineering or a closely related discipline
  • Research experience in X-Ray spectroscopy, scattering, atomic or plasma Physics
  • Ability to develop and apply quantitative methods for the analysis of experimental data
  • Experience in conducting experimental research, preferably at a large-scale research facility
  • Ability to do independent research while contributing effectively to a multidisciplinary team
  • Experience with scientific computing, preferably in python or comparable tools
The following qualifications would be beneficial:
  • Experience with resonant spectroscopic techniques, such as resonant inelastic X-Ray scattering, resonant X-Ray emission spectroscopy, X-Ray absorption spectroscopy
  • Knowledge of atomic or electronic structure modelling, including density functional theory or collisional-radiative approaches
  • Familiarity with XFEL or synchrotron experiments
  • Background in warm dense matter, high energy density physics, laser driven plasmas or inertial fusion research

For additional information, please contact Oliver Humphries (oliver.humphries@xfel.eu).

Working place will be Schenefeld, in the Hamburg metropolitan area. General information on working in Germany, the Hamburg area and the European XFEL can be found on our Career Page.
