Design and Development of Depleted Monolithic Active Pixel Sensors with Small Collection Electrode for High-Radiation Applications
(2021-09-27)
Depleted monolithic active pixel sensors (DMAPS) have emerged as a low material and low cost alternative to the established hybrid technology. In this thesis, two large scale prototype chips that feature a fast column-drain ...
3D-Silicon and Passive CMOS Sensors for Pixel Detectors in High Radiation Environments
(2020-10-30)
The future upgrade of the Large Hadron Collider to the High-Luminosity LHC demands new pixel detectors that can operate in environments with exceptionally high radiation. This requires investigations into new radiation-tolerant ...
Studies into measuring the Higgs CP-state in H → ττ decays at ATLAS
(2020-07-16)
Since the discovery of the Higgs boson in 2012, experimental particle physics made large efforts to measure all properties of the new particle to characterise all its properties as precisely as possible.
So far, all ...

Measurement of the top quark decay branching fraction ratio Rb = B(t → Wb)/B(t → Wq) and of the inclusive production cross section pp → tt in the dilepton channel at ATLAS
(2022-01-13)
The top quark branching fraction ratio Rb and the inclusive production cross section σ tt̄ are measured in the dilepton channel using 4.6 fb-1 of proton-proton collisions at the centre-of-mass ...
Development and Characterisation of Passive CMOS Sensors for Pixel Detectors in High Radiation Environments
(2022-10-07)
With the upgrade of the Large Hadron Collider (LHC) to the High-Luminosity LHC (HL-LHC), the instantaneous luminosity increases by a factor of five with respect to its design value from 2027. To keep the detectors at the ...
Evaluation of a Serial Powering Scheme and its Building Blocks for the ATLAS ITk Pixel Detector
(2022-11-02)
The high luminosity upgrade for the Large Hadron Collider (LHC) at CERN requires a complete redesign of the current inner detectors of ATLAS and CMS. These new inner detectors will consist of all-silicon tracking detectors, ...
Characterization and Quality Control of RD53A Readout Chips and Modules for the ATLAS ITk Pixel Detector
(2021-12-16)
In preparation of the upcoming high-luminosity upgrade of the Large Hadron Collider, the detectors of the major high-energy physics experiments at the accelerator facility will be upgraded as well. In case of the ATLAS ...
