PhD Student to study & develop 2-colors opportunities at European XFEL

Website EuropeanXFEL European XFEL

Shaping the future

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 X-Ray Optics (XRO) group is responsible for the X-ray beam transport in the tunnels and shaft buildings of the facility before the experiment hall. This includes design and procurement of mirrors, monochromators, beam loss monitors, collimators and shutters, which are needed to ensure a safe and efficient use of X-ray beams at the experiments. The group also supports Scientific Instrument groups in conceptual design and implementation of X-ray optics around the experiments.

For our X-Ray Optics group we are looking for a

PhD Student (f/m/d) to study & develop 2-colors opportunities at European XFEL

The position

Two-color pump-probe spectroscopy is a very powerful tool to study the temporal evolution of an excited system or, more generally, to investigate the dynamics of a photoinduced process. At the European XFEL, a suitable X-ray device enabling experiments using a 2-colors pump-probe excitation scheme with adjustable time delay is under development. The thesis is a collaboration of the XRO group for the X-ray optical part and the SQS research team for the scientific part.
The specific tasks include:
  • simulation of the beam characteristics, heat load, damage issues of the Optical Delay Line (ODL)
  • participation to the technical commissioning of the magnetic chicane (MC)
  • first experiments with the 2-colors set-up at the SQS instrument using the MC
  • participation in installation and first commissioning of the ODL
  • participation in the technical commissioning and first experiments at the SQS instrument using the MC and the ODL together
  • Master’s degree in Physics
  • knowledge about x-ray optics would be a useful asset
  • previous experience with gas phase spectroscopic techniques at FELs, HHG sources or synchrotron radiation facilities
  • ability to work outside usual office working hours (during shift work periods working times include nights and weekends)
  • good communication skills in English and the ability to work in an international and multi-disciplinary team
