The current research program focuses on the investigation of hard X-ray radiation from charged particle collisions or photon-matter interactions.

Our special interest lies in the study of simple atomic systems in the widely unexplored domain of heavy high-Z ions in order to test and to advance our basic knowledge about the physics of strong fields. These investigations are complemented by the studies of processes which appear in high-intensity laser fields or at synchrotron facilities.

Within our experimental campaigns various X-ray detection systems such as standard X-ray detectors, 2D position-sensitive detectors, crystal spectrometers, X-ray CCDs and micro-calorimeters are used.

Our research group is part of the Institute for Optics and Quantum Electronics (IOQ) and the Helmholtz Institute JenaExternal link . Within the FAIR project we are part of the collaborations Stored Particle Atomic Physics Research Collaboration (SPARC)External link and Atomic, Plasma Physics and Applications (APPA)External link
