Coherent ionization dynamics induced by intense X-ray free-electron laser pulses
… by ultrashort and intense pulses from an (X-ray) free-electron laser are investigated with the objective to find appropriate conditions where coherent dynamics manifests itself in physical observables. The ionization dynamics induced by an X-ray or extreme ultraviolet laser pulse is typically …

Optische Kontrolle der Lasertätigkeit im Röntgenbereich
X-ray free-electron lasers have revolutionized x-ray science by achieving unprecedented intensities exceeding 10^18 W/cm^2. However, they lack temporal coherence and controllability of their pulses' temporal and spatial properties, which is essential for many applications. We investigate the …

Structural enzymology of soluble methane monooxygenase protein-protein interactions.
… crystals of the sMMOH:MMOB complex. Using X-rays generated by either an X-ray free electron laser at room temperature or a synchrotron at 100 K, we obtained high resolution structures of the Methylosinus trichosporium OB3b sMMOH:MMOB complex for the first time. Analysis of the data shows in …

Serial and Single Crystal Studies of Ligand Binding to Radiation Sensitive Haem Protein DHP-B
… study, including in room temperature, damage-free X-ray Free-Electron Laser (XFEL) structures, ruling out the possibility of the hemichrome species being from the use of cryoprotectant. More research needs to be done to determine whether the hemichrome species has any biological relevance. …

Ultrafast electron transfer and intersystem crossing in bimetallic molecules
Increasingly, the role of electron spin is an important topic in electron transfer (ET). Coupling between the electronic, spin, and nuclear degrees of freedom play an important role in driving ET and intersystem crossing (ISC) on the ultrafast timescale. In this thesis, ultrafast optical and X-ray …

Electron Beam Diagnostic at the ELBE Free Electron Laser
… the facility. ELBE is based on a superconducting electron linac. The linac consists of two accelerating modules and uses TESLA type nine-cell niobium cavities, two cavities in each module. The cavities were developed at DESY in the framework of the TESLA linear collider project and the X-ray free …
