 Measurement of $D^0-\overline{D^0}$ mixing parameters and search for $CP$ violation in $D^0 \rightarrow K^+ \pi^-$ decays with LHCb Run 2 data / Ribatti, Roberto (Universita & INFN Pisa (IT)) $D^0-\overline{D^0}$ mixing parameters are measured in the decay-time-dependent ratio of $D^0 \rightarrow K^+ \pi^-$ to $D^0 \rightarrow K^- \pi^+$ rates. The analysis uses a data sample of proton-proton collisions corresponding to an integrated luminosity of $5.9\,\text{fb}^{-1}$ collected by LHCb experiment from 2015 to 2018 at the center-of-mass energy of $13$ TeV.

 Finite Element Analysis of Magneto-Thermal Transient Effects in Superconducting Accelerator Magnets / Wilczek, Michal (Lodz Technical University (PL)) In this thesis, an electro-thermal multidimensional model is constructed in ANSYS APDL to simulate self-protectability scenarios of superconducting magnets. The analysis takes the longitudinal and the turn-to-turn quench propagation into account. [...] CERN-THESIS-2020-006.- 141 p. Fulltext: PDF; External link: Approve this document (restricted)

 Anomaly detection for the injection kickermagnets of the CERN Large HadronCollider / Dewitte, Thiebout Thomas Reliability, availability and maintainability are parameters that determine if a large-scale accelerator system can be operated in a sustainable and cost effective manner. Beam transfer equipment such as kicker systems are critical components with potential significant impact on the global performance of the entire machine complex [...] CERN-THESIS-2019-294.- 85 p.

 LHC status and performance / Wenninger, Jorg (CERN) The CERN Large Hadron Collider operated during Run 2 (2015-2018) at a beam energy of 6.5 TeV. This period saw an important increase in performance through improvements in the LHC and an increased beam quality from its injectors, leading to a peak luminosity that exceeds the LHC design luminosity by more than a factor two.

 Improvement of the CERN SPS electrostatic septa ion traps / Balhan, B (CERN) ; Barlow, R A (CERN) ; Borburgh, J (CERN) ; Raffaele, G (Bari Polytechnic) At CERN, the SPS synchrotron is equipped with a slow extraction channel towards the fixed target beam lines in the North Area This channel includes five consecutive electrostatic septa, where the field free region and the active high field region are separated by an array of tungsten-rhenium wires. The field-free region provides for the circulating beam, while the high field region is used to deflect the extracted beam.
