The silicon strip detector of the ATLAS Inner Tracker: from individual sensing units to multi-module petal structures
[DESY-THESIS-2022-008]
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 153 pp. (2022) [10.3204/PUBDB-2022-01931]2022 = Dissertation, University of Dortmund, 2022
Nowadays particle detector technology is taking big steps forwards and new devices dedicated to particle physics show very high performance. Particularly the semi-conductor detectors have advanced significantly and are used for tracking purposes in the A Toroidal LHC ApparatuS (ATLAS) experiment at CERN thanks to their excellent spacial resolution: the compact size of the silicon and its high granularity allow to reach a precision measurement of few tens of microns.This thesis is focused on the upgrade of the ATLAS tracking detector required for the High Luminosity Large Hadron Collider (HL-LHC), starting in 2027.

Tailoring Heat Treatments for Metals Processed by Laser Powder Bed Fusion
The project's main goal is to design tailored post-process heat treatments for four LPBF high-end alloys (AlSi10Mg, AlSi7Mg, Ti6Al4V ELI, Inconel 718) that are widely used in the Aerospace, Healthcare, and Energy industry. The precondition for a successful design of the tailored heat treatment is the guarantee that mechanical property standards for the Aerospace, Healthcare, and Energy industry are met at any time.

Molecular modeling at high X-ray intensity: Developments, applications and challenges
1-130 (2022)2022 = Dissertation, Universität Hamburg, 2021
The advent of X-ray free-electron lasers (XFELs) over the past decade, providing ultraintense femtosecond X-ray pulses, offers novel opportunities formolecular structure investigations. By now, most of the established approachesrevolve around diffractive imaging schemes with crystalline samples, whereelectronic and nuclear radiation damage, caused by the X-rays, must be avoidedto achieve the highest possible spatial resolution.

Search for top quark-antiquark pair resonances with the ATLAS experiment
211 pp. (2022)2022 = Dissertation, Humboldt-Universität zu Berlin, 2021
AbstractA search for new heavy particles that decay into top quark-antiquark pairs ispresented using an integrated luminosity of 20.3 fb−1 of proton-proton collision datarecorded at a centre-of-mass energy of √s = 8 TeV with the ATLAS experiment atthe Large Hadron Collider. The analysis considers events with exactly one chargedlepton, missing transverse momentum and jets in the final state. [...]
