The time-dependent Schrödinger equation was solved for a reduced-dimensionality description of the cluster, taking into account overall rotations and the internal rotation of the water moiety.

Cold Beams of Large Molecules for Structural Dynamics Studies Hamburg 123 pp. (2018) [10.3204/PUBDB-2018-04495] = Dissertation, Universität Hamburg, 2018   Biomolecules and their reactions are of great interest because they are important for the functions in our body and thus for health. The structure of a molecule defines its function, and in this work we demonstrate the crucial steps that will allow direct recording of structural information from large biological molecules through gas-phase x-ray di↵raction.

Optical and aerodynamic focusing of isolated particles for diffractive imaging experiments at X-ray free electron lasers [DESY-THESIS-2018-034] Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 191 pp. (2018) [10.3204/PUBDB-2018-04428] = Dissertation, Universität Hamburg, 2018   The highly brilliant, short and coherent pulses produced by X-ray free-electron lasers (XFELs) opened up a unique opportunity to image small objects in nature, such as protein macromolecules, clusters, viruses and nanoparticles with nearly atomic spatial resolution, and their dynamic processes can be probed with femtosecond temporal resolution. Single-particle imaging (SPI) is a coherent diffraction imaging technique at XFELs that consists of directing a stream of randomly oriented isolated bio-particles across the focus of the X-ray beam to construct high-resolution 3D structure from diffraction patterns of multiple identical particles.

The spatial separation of different molecular species from each other as well as from atomic seed gas is improved. [...] Published on 2018-09-20.

A velocity-map-imaging spectrometer is demonstrated to characterize the normalized transverse emittance of photoemitted electron bunches.
