The SLD vertex detector upgrade (VXD3) and a study of bbg events
… the design, construction and use of the SLD's vertex detector. SLD's pioneering 120 Mpixel vertex detector, VXD2, was replaced by VXD3, a 307Mpixel CCD vertex detector in January 1996. The motivation for the up-grade detector and its subsquent construction and testing are described in some …

Analysis of 3D silicon pixel vertex detector damage effects due to radiation levels present in the LHC at CERN
… of charged particles is needed. Solid state detectors achieve the high precision necessary to provide track and vertex reconstruction of the particles that traverse them, but tracking performance begins to deteriorate at fluxes of radiation around 10¹⁴ - 10¹⁵ hadrons/cm 2. These radiation …

Resolution Studies for the Micro Vertex Detector of the PANDA Experiment and the Reconstruction of Charmed Mesons for Specific Hadronic Channels
… studies of hadronic systems an universal detector is being designed, the PANDA detector. A high resolution Micro Vertex Detector (MVD), as part of the whole setup, is an important component of the track and vertex reconstruction. A mayor part of this work were simulation studies to …

Measurement of B-hadron masses at CDF run II
… effects in the Central Outer Tracker and Silicon Vertex Detector, apply and fine tune the energy loss corrections per track, and finally tune the magnetic field scale. With the momentum scale established, we find: m(B⁺) = 5279.10 ± 0.41 (stat) ± 0.36 (sys), m(B⁰) = 5279.63 ± 0.53 (stat) ± 0.33 …

Radiation damage effects in charge coupled devices
… by the need to qualify CCDs for the SLD vertex detector. However, the work is also relevant to other small signal, low noise applications. The results of the batch qualification are presented and the data base of ionising radiation effects on EEV CCDs has been extended to include the …

Development and Characterisation of a Radiation Hard Readout Chip for the LHCb-Experiment
… channel pipelined readout chip for silicon strip detectors. The front-end consists of a charge-sensitive preamplifier and a CR-RC pulse shaper. It features an equivalent noise charge of ENC = 497 e + 48.3 e/pF Cin. The analogue memory is a switched capacitor array, which provides a latency of max. …

Development, Optimisation and Characterisation of a Radiation Hard Mixed-Signal Readout Chip for LHCb
… channel pipelined readout chip for silicon strip detectors. The front-end consists of a charge-sensitive preamplifier followed by a CR-RC pulse shaper. The analogue pipeline memory is implemented as a switched capacitor array with a maximum latency of 4us. The 128 analogue channels are multiplexed …

Innovative silicon pixel sensors for a 4D VErtex LOcator detector for the LHCb high luminosity upgrade
… also in the high luminosity condition, several detectors will have to be upgraded or replaced and this is particularly true for the VErtex LOcator (VELO). In fact, dedicated simulations have shown a significant decrease of the vertices and tracks reconstruction efficiencies of the current VELO …

Calorimetry at a Future Linear Collider
… and the International Linear Collider (ILC). The detector design of these experiments is built around high-granularity Particle Flow Calorimetry that, in contrast to traditional calorimetry, uses the energy measurements for charged particles from the tracking detectors. This can only be realised …

Quality assurance of the VELO modules and analysis of the Bd->K*\mu^+\mu^- rare decay on LHCb
The LHCb experiment is a high energy physics detector at the Large Hadron Collider. The experiment has been designed and built to search for new physics in the b hadron sector. This thesis discusses a contribution to the detector construction and preparatory studies for a rare decay analysis. …
