Neural Network based Pulse Shape Analysis with the Belle II Electromagnetic Calorimeter
Hamburg 89 pp. () = Masterarbeit, University of Hamburg, 2021
The Belle II experiment, located at the SuperKEKB e+e- collider inJapan, uses pulse shape analysis techniques to distinguish electromagneticallyand hadronically interacting particles within the CsI(Tl) electromagneticcalorimeter. The pulse shapes from the particle-dependent scintillationresponse are nominally analysed with a multi-template oine t to measurethe fraction of scintillation emission produced by hadrons [...]

A Search for High-Energy Neutrinos from Core-Collapse Supernovae
92 pp. () = Masterarbeit, Humboldt Universität zu Berlin, 2020
Since the discovery of high energetic cosmic rays their origin poses an open question. High- energy neutrino emission is considered a smoking-gun signature of cosmic ray production. [...]

Optimizing the triggering strategy for the detection of cosmic rays with the Radio Neutrino Observatory Greenland (RNO-G)
90 pp. () = Masterarbeit, Humboldt Universität zu Berlin, 2020
A promising technique to measure neutrinos above 10 PeV is the detection of radio signals generated by the Askaryan effect. The effect is caused by neutrino-induced particle cascades in dense media e.g. [...]

Optimizing the Machine Learning techniques in the $\it H$ $\rightarrow$ $\tau \tau$ analysis with CMS data
[DESY-THESIS-2021-001]
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 82 pp. () [10.3204/PUBDB-2021-01074] = Masterarbeit, Universität Hamburg, 2021  GO
This work is dedicated to optimize and improve the machine learning techniques usedin the $\it H$ $\rightarrow$ $\tau \tau$ analysis in the channel where the tau leptons decay to a e $\mu$ pair. The measurement is performed using data, corresponding to an integrated luminosity of 59.7 fb$^{-1}$, collected by the CMS experiment at a center-of-mass energy of 13 TeV during 2018. [...]

Production of coherent 150 nm light via 7$^{\text{th}}$ harmonic generation for nuclear spectroscopy applications
Hamburg 87 pp. () = Masterarbeit, University of Hamburg, 2021
The $7^{\text{th}}$ harmonic generation of $1030\,\text{nm}$ light constitutes a rather unexplored regime within the field of harmonic generation. The resulting coherent light with a wavelength of roughly $150\,\text{nm}$ can be utilized for a wide range of novel applications, in particular the recently emerging field of nuclear spectroscopy of the Thorium-229 isotope nucleus.

Paving the way of high repetition rate laser wakefield acceleration by solving heat induced grating deformation issues
62 pp. () [10.3204/PUBDB-2020-05063] = Masterarbeit, University of Hamburg, 2020  GO
The goal of this thesis was to enable high repetition rate Laser Wakefield Acceleration(LWFA) by solving heat induced grating deformation issues in a Chirped PulseAmplification (CPA) based 25 TW Ti:sapphire laser system centred at 800 nm. Thesepreviously limited the intensity and wavefront quality of the pulse. [...]
