The advancement of particle physics through current and future collider facilities pushes theboundaries of technology in HEP instrumentation. Experiments at the energy and intensityfrontier focus on high-precision measurements of Standard Model physics and searches forphysics beyond the Standard Model. [...]

The High-Luminosity Large Hadron Collider (HL-LHC) represents a significant leap inthe pursuit of fundamental physics. Scheduled to operate at a center-of-mass energy of14 TeV and a peak instantaneous luminosity up to 7. [...]

This thesis presents a search for supersymmetry using 138 fb−1 of proton-proton collisionat center-of-mass energy of √s = 13 TeV. The data was collected by the CMS detectorat the LHC at CERN in 2016–2018. [...]

In High-Energy Physics, detailed and time-consuming simulations are neededto describe particle showers in calorimeters. These particle showers arerecorded as energy deposits (hits) in the cells of the detector. [...]

This thesis addresses key challenges in modern particle physics by contributing to threecritical areas: the development of particle detectors, their calibration and the analysis ofdata collected in particle physics experiments. Contributions to these areas are presentedin the context of the Compact Muon Solenoid (CMS) experiment at the Large HadronCollider (LHC).The first part of this work focuses on the development and characterization of a temperaturetest system (Burn-in) for silicon modules, essential components of the CMS OuterTracker Upgrade, a central part of the preparation of CMS for the forthcoming High LuminosityLHC running [...]

The development of ultra-low emittance storage rings, such as the e+/e- Future CircularCollider (FCC-ee) with a circumference of about 90 km, aims to achieve unprecedentedluminosity and beam size. One significant challenge is correcting the optics, which becomesincreasingly difficult as we target lower emittances [...]

Nach ihrer Erschaffung genießt Nelly, das astrophysikalische Neutrino, alles, was sie im Universum sieht. Doch der Weltraum kann einsam sein [...]

It is a fundamental problem in photon science that at X-ray energies, the oscillation frequency of the electromagnetic field is so high that a detector cannot measure the phase of an interacting object. This ‘phase problem’ also occurs in measurements of an object’s atomic-level properties using recoilless nuclear resonant scattering (NRS) of pulsed synchrotron radiation, which is based on the Mössbauer effect.In this thesis, we demonstrate how to use a ptychographic scanning technique to perform computational phase retrieval for an object in the energy domain via overlapping NRS measurements in the time domain. [...]

Compact high-brightness electron beam sources are advantageous for industrial, medicaland scientific applications. Laser-plasma acceleration has the potential to meet thisneed, as it can provide acceleration fields that are orders of magnitude higher than inclassical linear accelerators based on modern radio-frequency technology, allowing formuch smaller accelerators. [...]

This thesis investigates the optimization of a Transition-Edge Sensor (TES) for the Any Light Particle Search II (ALPS II) experiment. The ALPS II experiment searches for axions and axion-like particles, which are predicted by several beyond-standard model theories and are good candidates for dark matter. [...]
