Beschreibung: The goal of the project is the development of methods for real-time data reduction for X-ray Photon Correlation Spectroscopy (XPCS) using FPGAs (in collaboration with computer scientists) and to apply XPCS to study dynamic processes in condensed matter. The focus lies on dynamic phenomena in energy storage materials such as Li-ion batteries. Scientific questions of interest center on dynamics in polymer electrolytes, ion transport in water-in-salt electrolytes, and Li diffusion in garnets.

The project involves travel to international user facilities such as ESRF (Grenoble), DESY (Hamburg), SSRL (Stanford), and APS (Chicago). Additionally, a new high-end laboratory multipurpose X-ray diffractometer will be employed.

- Commissioning of an X-ray detector and implementation and verification of real-time FPGA calculations of autocorrelation functions from data acquired with it.
- Fabrication and characterization of electrode materials for batteries.
- Investigation of the dynamics in these materials by means of X-ray Photon Correlation Spectroscopy (XPCS).
- Participation in synchrotron beamtimes.
- Publication of the obtained results in scientific journals.
- Teaching duties to the extent of 2 SWS.

The position is initially limited until 30.09.2025.
