PhD Position (f/m/d) - part time (75%)

X-ray Spectroscopy with Quantum Sensors at the KIT Light Source

Novel quantum sensors, such as magnetic microcalorimeters (MMCs) promise to be the next generation of detectors for x-ray spectroscopy at synchrotron light sources, offering either higher transmission or higher resolution than existing technologies.

Tätigkeitsbeschreibung

As part of the interdisciplinary research project QS4Physics, you will work on developing a platform that enables the integration of such sensors into existing synchrotron beamlines at the KIT Light Source.

In addition, you will perform x-ray spectroscopic measurements on applied material systems. These experiments will be conducted using both existing “conventional” x-ray spectrometers and the newly developed quantum sensor systems at the KIT Light Source, both in the soft and hard x-ray regime.

You will collaborate in an interdisciplinary team and contribute to cutting-edge research at the interface between detector physics and materials research.

Your tasks will include:

  • Develop a detector platform to integrate MMCs with existing synchrotron beamlines (such as the X-SPEC beamline at the KIT Light Source)
  • Develop and test infrared blocking filters with high transmission in the soft and hard x-ray range
  • Perform soft and hard electron and x-ray spectroscopy experiments on applied material systems using various beamlines at the KIT Light Source
  • Present your results at international conferences and publishing in peer-review journals

This position is intended to lead to a PhD in Physics or Chemistry.

Persönliche Qualifikation
  • Masters/Diploma in Physics, Chemistry, Materials Science, or equivalent
  • Hands-on experience with ultra-high vacuum (UHV) systems
  • Ideally background in soft and/or hard x-ray and electron spectroscopies (emission, absorption, photoelectron spectroscopy)
  • Enthusiasm for team-based and interdisciplinary science, with a focus on detector development and applied material systems
  • Good English skills (written and spoken); German skills are helpful, but not required
