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.
The Spectroscopy and Coherent Scattering (SCS) instrument provides a unique opportunity to study the ultrafast science of quantum materials using advanced soft X-ray spectroscopy techniques at a high-repetition-rate X-ray free-electron laser (FEL) source. The installation and commissioning of a THz and mid-IR source at the SCS instrument is underway for first user experiments, which are planned for 2026. To lead and support these efforts, the SCS group is looking for an
Instrument Scientist (f/m/d) in Ultrafast X-ray Science of Quantum Materials using THz/mid-IR sources
The Position
- Investigate THz-/MIR-driven quantum materials with soft X-ray spectroscopy and diffraction (XAS, RIXS, XRD)
- Work with Laser group to implement and deliver THz and mid infrared sources
- Set up laser delivery to end stations for user experiments
- Characterize laser pulses at the target position
- Find timing between the optical and x-ray laser pulses at the beginning of each experiment
Requirements
- PhD-degree in experimental physics or chemistry
- Experience in ultrafast material dynamics studies using THz-/MIR- excitations
- Experience with femtosecond lasers
- Experience at large scale facility (e.g. SR, FEL) would be an asset
- Knowledge in UHV and X-ray spectroscopy would be advantageous
- Strong motivation to participate in SCS user support program and collaborations
- Strong motivation to develop own research profile in SCS user support program and collaborations
- Strong motivation in optical laser development in strategic directions for the SCS instrument
- Excellent communication skills and the ability to work in a multi-lingual, multi-disciplinary team
