High purity X-ray polarimetry and X-ray spectroscopy

Homepage: X-Ray Optics

The topics of our group are the precise measurements of x-ray emission spectra and the precise determination of the polarization states of different x-ray sources such as highly excited matter (plasma, ions) and new x-ray sources such as synchrotrons of third generation and X-ray Free-Electron Lasers. In addition, we investigate methods for the detection of small polarization changes introduced by various samples like thin films or magnetic structures. In order to understand the physical processes observed by our techniques, we have developed highly sophisticated experimental and simulation methods to understand the detailed processes of our x-ray diagnostic systems. The applied methods are used in different fields of physics for instance in solid state physics, quantum electrodynamics, and plasma physics.
