Development of the Detector Readout for the ATLAS Phase II ITk Pixel Detector
During the HL-LHC upgrade, a high luminosity upgrade takes place, where the instantaneous luminosity will reach 7.5 × 10^(34) cm^(-2)s^(-1) in Run 4. The current inner detector of the ATLAS experiment will be replaced by an all-silicon detector called the Inner Tracker (ITk). The ITk comprises a pixel detector surrounded by a strip detector. The pixel detector consists of five layers, with the first two layers forming the inner system and the last three layers forming the outer barrel and the endcap. Due to the large number of components, a database named the ITk production database (ITk PD...
The Read-Out Controller ASIC for the ATLAS Experiment at LHC
This thesis presents the complete chain from specifications to real-life deployment of the Read Out Controller (ROC) ASIC for the ATLAS Experiment at LHC, including the design of the FPGA-based setup used for prototype validation and mass testing of the approximately 6000 chips. Long-lasting experiments like the ATLAS at the LHC undergo regular upgrades to improve their performance over time. One of such upgrades of the ATLAS was the replacement of a fraction of muon detectors in the forward rapidities to provide much-improved reconstruction precision and discrimination from background protons. This new instrumentation (New Small Wheel) is equipped with custom-designed, radiation-hard, on-detector electronics with the Read Out Controller chip being a mission-critical element. The chip acts as a clock and control signals distributor and a concentrator, buffer, filter and real-time processor of detector data packets. The described and deployed FPGA-based test setup emulates the asynchronous chip context and employs optimizations and automatic clock and data synchronization. The chip's tolerance to nuclear radiation was evaluated by recording its operation while controlled ultrafast neutron beams were incident to its silicon die. Predictions for the operating environment are made. A proposed implementation of an FPGA Integrated Logic Analyzer that mitigates the observed limitations and constraints of the existing ones is included.
Search for Higgs Boson Decays to Charm Quarks with the ATLAS Experiment and Development of Novel Silicon Pixel Detectors
This book explores the Higgs boson and its interactions with fermions, as well as the detector technologies used to measure it. The Standard Model of Particle Physics has been a groundbreaking theory in our understanding of the fundamental properties of the universe, but it is incomplete, and there are significant hints which require new physics. The discovery of the Higgs boson in 2012 was a substantial confirmation of the Standard Model, but many of its decay modes remain elusive. This book presents the latest search for Higgs boson decays into c-quarks using a proton-proton collision dataset collected by the ATLAS experiment at the Large Hadron Collider (LHC). This decay mode has yet to be observed and requires advanced machine learning algorithms to identify c-quarks in the experiment. The results provide an upper limit on the rate of Higgs boson decays to c-quarks and a direct measurement of the Higgs boson coupling strength to c-quarks. The book also discusses the future of particle physics and the need for significant improvements to the detector to cope with increased radiation damage and higher data rates at the High-Luminosity LHC. It presents the characterization of the ATLAS pixel detector readout chip for the inner detector upgrade (ITk). The chip was subjected to irradiations using X-rays and protons to simulate the radiation environment at the HL-LHC. The tests showed that all readout chip components, including the digital logic and analogue front-end, are sufficiently radiation-tolerant to withstand the expected radiation dose. Finally, this book describes monolithic pixel detectors as a possible technology for future pixel detectors. This book is ideal for individuals interested in exploring particle physics, the Higgs boson, and the development of silicon pixel detectors.
