Acceleration and Phase Space Manipulation of Relativistic Electron Beams in Nano- and Micrometer-Scale Dielectric Structures [DESY-THESIS-2019-025] Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 215 pp. (2019) [10.3204/PUBDB-2019-03861] = Dissertation, Universtät Hamburg, 2019   This thesis is about simulations, proof-of-principle experimental setups and first test experiments for new ultra-compact particle accelerators based on dielectric structures. Due to the high damage threshold of nano- and micrometer-scale dielectrics in the optical regime, accelerating fields on the order of GV/m can be achieved.

Development of a compact hard X-ray split-and-delay line for studying ultrafast dynamics at free electron laser sources [DESY-THESIS-2019-023] Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 140 pp. (2019) [10.3204/PUBDB-2019-03551] = Dissertation, Universität Hamburg, 2019   The study of condensed matter dynamics on ultrafast timescales is one of the key topics in modern material science research. Hard X-ray free-electron laser sources with extreme peak brightness and ultra short pulses provide excellent conditions for studying ultrafast dynamics in the time domain by employing such techniques as X-ray pump-probe spectroscopy or X-ray photon correlation spectroscopy.

Parametric Waveform Synthesis [DESY-THESIS-2019-021] Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 172 pp. (2019) [10.3204/PUBDB-2019-03351] = Dissertation, Universität Hamburg, 2019   The coherent synthesis of pulses from Optical Parametric Amplifiers (OPAs) offers the possibility to realize field-controlled electromagnetic waveforms with sub-cycle durations, widely scalable in energy and spectral bandwidth.Here we demonstrate a fully functional prototype of a mJ-level two channel parametric waveform synthesizer, which is ready to be upgraded to three channels. The synthesized field, whose bandwidth covers more than 2 octaves, from ~500 nm to ~2200 nm, can be compressed to a non-sinusoidal sub-cycle waveform close to the transform-limit.The long term stable operation of such a complex laser source is achieved, for the first time, by means of a sophisticated optical and mechanical design of the whole OPA system, along with targeted improvements made to the commercial pump laser.A new seeding scheme based on multiple supercontinua, further scalable to the mid-IR, leads to excellent phase stability among the different OPA channels and to a simplified dispersion management scheme.A detailed study, both theoretical and experimental, of the couplings among different pulse parameters during the parametric amplification, unveiled novel details of the Carrier-Envelope-Phase (CEP) stabilization process via OPA, and guided the design of the CEP-controlled seeding front-end.A simplified two-dimensional spectral shearing interferometry setup, where the ancillary pulses are obtained by spectral filtering the pump pulses, has been developed to easily characterize the spectral phase of the ultrabroadband pulses from each channel, overcoming the limitation of second-harmonic-based methods.Furthermore, ad-hoc nonlinear optical techniques have been deployed to observe the most relevant synthesis parameters such as the CEP of the seeding pulses and the relative phase among the different channels outputs.

Search for supersymmetry with tau leptons in the CMS experiment [DESY-THESIS-2019-020] Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 205 pp. (2019) [10.3204/PUBDB-2019-03086] = Dissertation, Universität Hamburg, 2019   This thesis is focused on the search for pair production of the supersymmetric $\tau$ lepton partners within the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC). The search is performed using the data collected at a center-of-mass-energy $\sqrt{s} = 13$ TeV with the CMS detector in the years 2016-2017.One of the most popular extensions of the Standard Model (SM) is supersymmetry (SUSY).
