Characterisation of CMOS Sensors for the Belle II Vertex Detector Upgrade
(2024-07-12)The Belle II experiment at KEK in Japan plans to upgrade the SuperKEKB accelerator by the end of the decade. This gives rise to the opportunity to upgrade the current vertex detector system to address the high background ... -
Characterisation, optimisation and performance studies of pixel vertex detector modules for the Belle II experiment
(2021-10-13)The Standard Model of particle physics is very successful in describing the fundamental particles and their interactions. Still, some questions regarding the details and input parameters of the theory, as well as regarding ... -
Commissioning and first data taking experience with the Belle II pixel vertex detector
(2020-07-01)The Belle II experiment at the SuperKEKB particle accelerator at KEK in Tsukuba (Japan) is the successor to the Belle experiment, which played a crucial role in the discovery of CP violation in the B-Meson system. The ... -
Radiation length measurements with high-resolution telescopes
(2019-08-27)The radiation length imaging method presented in this work can be used to conduct spatially resolved measurements of scattering angles of particles traversing a object under study. For the measurements a planar object is ... -
Search for Supersymmetry in Trilepton Final States with the DØ Experiment
(2015-10-27)A search for supersymmetry in the trilepton final state is performed using the full dataset of the DØ experiment. The analyzed data amounts to an integrated luminosity of ∫ℒ = 9.7 fb⁻¹ of pp̅ collisions, produced at √s ... -
Monitoring Radiation Damage in the ATLAS Pixel Detector
(2014-11-05)Radiation hardness is one of the most important features of the ATLAS pixel detector in order to ensure a good performance and a long lifetime. Monitoring of radiation damage is crucial in order to assess and predict the ... -
Testbeam Measurements with Pixel Sensors for the ATLAS Insertable b-Layer Project
(2014-07-04)During the current long machine shutdown of the Large Hadron Collider (LHC) at CERN (Geneva), the innermost part of the ATLAS experiment, the pixel detector, is upgraded. The existing ATLAS pixel system is equipped with ... -
Untersuchung der elektrischen Hyperfeinwechselwirkung in M<sub>n+1</sub>AX<sub>n</sub>-Phasen mittels der gestörten γ-γ-Winkelkorrelation
(2014-05-19)Mn+1AXn phases are thermodynamically stable nanolaminated ternary carbides and nitrides showing both metallic and ceramic properties. The letter M stands for an early transition metal, the letter A represents an A-element ... -
Electrical characterization of conductive ion tracks in tetrahedral amorphous carbon with copper impurities
(2014-01-10)The irradiation of tetrahedral amorphous carbon (ta-C) with swift heavy ions leads to the formation of conductive microscopic ion tracks with diameters of about 10 nm. This phenomena depends on the sp² to sp³ hybridization-ratio ... -
Development of the readout for the IBL Upgrade Project of the ATLAS Pixel Detector
(2012-12-05)The LHC luminosity is upgraded in several phases until 2022. The resulting higher occupancy degrades the detector performance of the current Pixel Detector. To provide a good performance during the LHC luminosity upgrade, ... -
Measurement of the Top Quark Pair Production Cross Section and Simultaneous Extraction of the W Heavy Flavor Fraction at √s = 7 TeV with the ATLAS Detector at the LHC
(2012-04-27)The top quark pair production cross section, σtt, is measured in the semileptonic channel in two datasets using a binned profiled likelihood template fit to data to discriminate the signal, tt, from its main background, ...
