Hamburg 66 pp. () = Universität Hamburg, Masterarbeit, 2014
AbstractPlasma-Wakeeld Accelerators are seen as a promising future technology for the generationof high-energy electron bunches at acceleration lengths which are much shorter thanthe ones needed for conventional linear accelerators. The main mechanism for this methodis based on the observation that plasma can sustain very high eld gradients, whichcan be excited by a high-intensity laser and then used for the acceleration of electrons.The prevalent method for the modelling of these processes are Particle-in-Cell simulations(PIC-Simulations), which oer an accurate depiction of the associated physical propertieswithin their numerical boundaries.

GEM Luminosity Monitors for the Olympus Experiment to determine the Effect of Two-Photon Exchange

The OLYMPUS experiment at DESY acquired its data in two distinct periods between 2012-2013 to measure the ratio of positron-proton and electron-proton elastic scattering cross sections. In light of those measurements, OLYMPUS will be able to quantify the effect of two-photon exchange, which is widely considered to be responsible for the discrepancy between measurements of the proton electric to magnetic form factor ratio with the Rosenbluth separation and polarization transfer methods.

Imaging Molecular Structure with Photoelectron Diffraction
Heidelberg University, Diss., 2014
The possibility to study the structure of polyatomic gas-phase molecules by photoelectron diffraction is investigated with the goal of developing a method capable of imaging ultrafast photochemical reactions with femtosecond temporal and sub-Ångström spatial resolution. The fluorine 1s-level of adiabatically laser-aligned 1-ethynyl-4-fluorobenzene (C8H5F) molecules was ionized by X-ray pulses from the Linac Coherent Light Source Free-Electron Laser, and the angular distributions of photoelectrons with kinetic energies between 30 and 60 eV were recorded by velocity map imaging.

High harmonic generation (HHG) is a fascinating strong-field physics phenomenon that occurs when a laser pulse with a moderate intensity interacts with atoms and partially ionizes the atoms. A series of harmonics are generated at similar efficiencies and extend to a few tenth, even thousandth, order harmonics at the extreme ultraviolet (EUV) and soft X-ray range. [...]

Correlated Nuclear and Electronic Dynamics in Photoionized Systems studied by Quantum and Mixed Quantum-Classical Approaches
[DESY-THESIS-2014-026]
Hamburg : DESY () [10.3204/DESY-THESIS-2014-026] = University of Hamburg, Diss., 2014  GO
The advent of free electron lasers and high harmonic sources enables the investigation of electronic and nuclear dynamics of molecules and solids with atomic spatial resolution and femtosecond / attosecond time resolution, using bright and ultrashort laser pulses of frequency from terahertz to hard x-ray range.With the help of ultrashort laser pulses, the nuclear and electronic dynamics can be initiated, monitored and actively controlled at the typical time scale in the femtosecond to attosecond realm. Meanwhile, theoretical tools are required to describe the underlying mechanism.This doctoral thesis focuses on the development of theoretical tools based on full quantum mechanical multiconfiguration time-dependent Hartree (MCTDH) and mixed quantum classical approaches, which can be applied to describe the dynamical behavior of gas phase molecules and strongly correlated solids in the presence of ultrashort laser pulses.In the first part of this thesis, the focus is on the motion of electron holes in gas phase molecular ions created by extremeultraviolet (XUV) photoionization and watched by spectroscopic approaches.

Analysis of the Stability of Monoclonal antibodies during Acidic Incubation and Neutralization
1-86 () = University of Copenhagen, Masterarbeit, 2014
In the commercial manufacturing of monoclonal antibodies (mAbs), several of the downstream operational steps such as chromatographic purification and endogenous retrovirus inactivation involve low-pH treatment, which potentially cause protein aggregation. Due to the high production cost of therapeutic proteins, and in order to avoid immunogenic reactions in patients arising from impurities in the product, it is of great importance for the pharmaceutical industry to have a thorough understanding of how and when acid-induced aggregation processes occur, and if they can be reversed.In this thesis, the stability of three different mAbs (IgG1, IgG2 and IgG4) during low-pH incubation in NaCl or sucrose, and their subsequent neutralization, has been characterized in a time-dependent manner.

Constraining Weakly Interacting Slim Particles with a Massive Star and in the Laboratory
[DESY-THESIS-2014-001]
Hamburg 151 pp. () = University of Hamburg, Diss., 2014
This doctoral thesis is devoted to constraining the allowed parameter space of weakly interacting slim particles (WISPs). WISPs are predicted by many extensions of the Standard Model of Particle Physics (SM): The Peccei-Quinn solution of the strong CP-problem of quantum chromo dynamics requires the existence of an axion; some embeddings of the SM into string theories predict a large number of axion-like particles (ALPs), the so called axi-verse, and hidden photons (HPs).

Measurement of spectral cut-offs of the active galactic nucleus MRK 421 with Veritas
Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät 153 pp. () [10.18452/17124] = Dissertation, Humboldt Universität, 2014  GO
VERITAS, an array of four imaging atmospheric Cherenkov telescopes, is capable of measuring spectra of very-high-energy (E > 100 GeV) γ-rays with high precision. On the basis of these spectra, conclusions can be drawn about the acceleration mechanisms in γ-ray sources. [...]

Time-resolved imaging of magnetic nanostructures in the visible and soft X-ray spectral range
München : Verlag Dr. Hut () = Universität Hamburg, Diss., 2014
To unravel the nature of magnetism, an investigation at its fundamental length- and time-scales has to be tackled. Besides pure research interest of the processes occurring in nanoscopic magnetic systems in the femto- and picosecond range, advancing knowledge experiences promising applications toward faster non-volatile memory devices with increased data storage density.

Study of the Silicon Photomultipliers and Their Applications in Positron Emission Tomography
[DESY-THESIS-2014-013]
Hamburg 119 pp. () = University of Hamburg, Diss., 2014
This thesis deals with silicon photomultipliers (SiPM) used in scintillation detectors and their applicationsin positron emission tomography (PET). The study of the SiPM is mainly focused on the application to theproposed EndoTOFPET-US detector, which is a multi-modality PET detector facilitating the developmentof new biomarkers for pancreas and prostate cancers.A Monte Carlo simulation tool is developed for the optimization of the detector’s single channel design.In order to obtain a 200 ps system coincidence time resolution and maximize the detector sensitivity, therequirements for the crystal geometry, light yield and SiPM photon detection efficiency are specifiedbased on the simulation study.

126 pp. () = Dissertation, University of Hamburg, 2013
This thesis reports on the development and application of two different but complementary ultrafast electron diffraction setups built at the Max Planck Research Department for Structural Dynamics. One is an ultra-compact femtosecond electron diffraction (FED) setup (Egun300), which is currently operational (with a maximum electron energy of 150 keV) and provides ultrashort (~300 fs) and bright (~10 e/um^(2)) electron bunches.
