GEM Luminosity Monitors for the Olympus Experiment to determine the Effect of Two-Photon Exchange
Hampton 265 pp. (2014) = Hampton University, Diss., 2014
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.

Around 2022, an upgrade of the LHC collider complex is planned to significantly increase the luminosity (the High Luminosity LHC, HL-LHC). This means that the experiments have to cope with a higher number of collisions per bunch crossing and survive in a radiation environment much harsher than that at the present LHC. [...]

The large number of top quarks produced in proton-proton (pp) collisions at the Large Hadron Collider facilitates precision measurements of top-quark properties that are crucial for testing the consistency of the Standard Model (SM) of particle physics. In particular, dierential measurements of the top-quark pair (t t ) production cross section are essential for comparison with state-of-the-art predictions of Quantum Chromodynamics (QCD) within the SM and for searches for new physics phenomena beyond it.

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 (2014) [10.3204/DESY-THESIS-2014-026] = University of Hamburg, Diss., 2014
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.

In this work digital Low Level Radio Frequency (LLRF) control techniques and procedures developed and successfully tested in the scope of the International Linear Collider (ILC) are described.One central requirement for the operation of ILC is the high gradient near (5% below) quench limit operation during the whole flattop of multiple cavities driven by a single klystron. In order to achieve such an operation, for every cavity the driving power (Pk) and the loaded quality factor (QL) have to be controlled individually. [...]

Analysis of the Stability of Monoclonal antibodies during Acidic Incubation and Neutralization
1-86 (2014) = 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.

Propagation of ultra-high-energy cosmic rays and their secondaries with CRPropa
[DESY-THESIS-2015-014]
Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 153 pp. (2015) [10.3204/DESY-THESIS-2015-014] = Universität Hamburg, Diss., 2014
Due to experiments like the Pierre Auger Observatory (Auger) and the Telescope Array (TA), high-statistics data is becoming available on the energy spectrum, the composition and the arrival directions of ultra-high-energy cosmic rays (UHECRs, cosmic rays with energies above $\sim 10^{17}$ eV). To interpret this data in terms of actual astrophysical parameters, or to test astrophysical models against the measured data, dedicated simulations of the propagation of UHECRs from their sources to Earth are needed.

Constraining Weakly Interacting Slim Particles with a Massive Star and in the Laboratory
[DESY-THESIS-2014-001]
Hamburg 151 pp. (2014) [10.3204/DESY-2014-03173] = Dissertation, University of Hamburg, 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).

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 (2014) = 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.

Hamburg 119 pp. (2014) [10.3204/DESY-2014-02771] = Dissertation, University of Hamburg, 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.

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.
