 Measurement of $K^+ \to \pi^+ \mu^+ \mu^−$ Decay Form Factor and Evaluation of Muon Veto and Charged Hodoscope Efficiencies at NA62 Experiment at CERN / Bician, Lubos (Comenius University (SK)) ; Cerny, Vladimir (dir.) (Comenius University (SK)) ; Koval, Michal (dir.) (CERN) The main focus of the presented thesis is the measurement of form factor parameters and branching fraction of a rare kaon decay $K^+ \to \pi^+ \mu^+ \mu^- (K_{\pi\mu\mu})$ at the NA62 experiment, using a sub-sample of data collected in 2017. In addition to the main $K_{\pi\mu\mu}$ analysis, efficiency evaluation studies for sub-detectors MUV3 and CHOD carried out by the author are summarized in the thesis.

 Characterization of impedance and wakefields of accelerator devices in the short bunch limit and beam dynamics effects for the CLIC Damping Rings / Passarelli, Andrea (Universita e sezione INFN di Napoli (IT)) ; Bartosik, Hannes (dir.) (CERN) ; Papaphilippou, Yannis (dir.) (CERN) ; Vittorio Giorgio, Vaccaro (dir.) (INFN sez. Naples) ; Boine-Frankenheim, Oliver (dir.) (TU Darmstadt) The Damping Rings (DRs) complex of the Compact LInear Collider (CLIC) has to provide ultra low emittances to the linear accelerating sections in order to reach a luminosity of $2\times10^{34}$ cm$^2$ s$^{-1}$ at the centre of mass energy $3$ TeV. Due to the high intensity, short bunches and low transverse emittances, collective effects are expected to seriously affect the performance of the DRs, limiting the electron and positron beam intensity at extraction, or causing an intolerable degradation of the beam quality [...] CERN-THESIS-2019-045.- Fulltext: PDF; External link: Approve this document (restricted)

 Protons Beyond the LHC Injectors Upgrade Project / Koukovini Platia, Eirini (CERN) ; Bartosik, Hannes (CERN) ; Forte, Vincenzo (CERN) ; Giovannozzi, Massimo (CERN) ; Huschauer, Alexander (CERN) ; Lasheen, Alexandre (CERN) ; Rumolo, Giovanni (CERN) ; Chapochnikova, Elena (CERN) The Large Hadron Collider (LHC) Injectors Upgrade (LIU) project is implementing major changes during the second long shutdown (LS2) across the injectors complex. The main aim of the project is to improve the performance of the accelerator chain for the production of LHC beams [...] CERN-PBC-REPORT-2019-004.- Geneva : CERN, 2019 - 35. Fulltext: PDF;

 Co-Simulation of Transient Effects in Superconducting Accelerator Magnets / Maciejewski, Michal (CERN) ; Auchmann, Bernhard (dir.) (CERN/PSI) ; Bartoszewicz, Andrzej (dir.) (Lodz University of Technology) Numerical modeling of complex physical systems involving several coupled physical domains, so called multi-domain and multi-physics systems, poses considerable challenges w.r.t. consistency of the formulation and selection of a suitable representation.
