Postdoctoral researcher for ultrafast X-ray and electron diffraction

Website EuropeanXFEL European XFEL

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.

The FXE (Femtosecond X-ray Experiments) scientific instrument at the European XFEL embraces several fields of ultrafast X-ray science and their applications by ultrafast pump–probe experiments on timescales below 100 femtoseconds.

Within the scope of a recently approved R&D project about ultrafast X-ray and MeV electron diffraction, we are now offering a position for:

Postdoctoral researcher for ultrafast X-ray and electron diffraction (f/m/d)
The position
  • Contribute to an assessment of the performance of MeV-UED beamline for measurement of ultrafast dynamics in close collaboration with the REGAE team.
  • Conduct a series of feasibility experiments using reference samples and perform in-house experiments with existing and potential users.
  • Process time-resolved diffraction data using existing and new software tools.
  • Explore diverse sample preparation methods for X-ray/electron diffraction.
  • Participate in user experiments (including limited shift work) and contribute to the scientific activities of the FXE group in EuXFEL
  • PhD degree in physics, chemistry or in a related discipline.
  • Proven research experience with ultrafast X-ray/electron diffraction and/or crystallography is required.
  • Experience in development and commissioning of time-resolved X-ray/electron diffraction instruments is an additional asset.
