1. 1. Demonstrating reliableinstrumentation in theATLAS Tile Calorimeter : Fault tolerance and redundancy in hardware and firmwarefor the Phase-II Demonstrator project in preparation forHigh Luminosity LHC at CERN

   Författare :Henrik Åkerstedt; Samuel B. Silverstein; Jón E. Gudmundsson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CERN; ATLAS; Tile calorimeter; TileCal; FPGA; SEU; TMR; Kintex; Demonstrator; DaughterBoard; Radiation testing; Radiation tolerant; Physics; fysik;

   Sammanfattning : The Large Hadron Collider at CERN is scheduled to undergo upgrades in 2026-2028 to significantly increase its luminosity. These upgrades, while providing the experiments with a higher collision rate, pose a number of challenges to the design of the hardware and software in the detectors. LÄS MER

3. 2. Development of the read-out link and control board for the ATLAS Tile Calorimeter Upgrade

   Sammanfattning : The Phase-II upgrade plan for the ATLAS Hadronic Tile Calorimeter facing the High-Luminosity LHC (HL-LHC) era includes approximately 1000 radiation tolerant read-out link and control boards (Daughterboards) that will provide full-granularity digital data to a fully-digital trigger system off-detector through multi-Gbps optic fibres. Different Daughterboard (DB) revisions have been developed, each successively aiming to meet the demanding HL-LHC requirements. LÄS MER

4. 3. Search for Charginos and Sleptons in ATLAS and Identification of Pile-up with the Tile Calorimeter

   Författare :Pawel Klimek; Christophe Clément; Barbro Åsman; Freya Blekman; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS experiment; particle physics; high energy physics; supersymmetry; SUSY; beyond standard model; chargino; neutralino; slepton; vector boson fusion; VBF; Tile calorimeter; TileCal; pile-up; quality factor; Large Hadron Collider; LHC; CERN; fysik; Physics;

   Sammanfattning : The standard model of particle physics (SM) describes the elementary particles and their interactions. Supersymmetry (SUSY), a symmetry beyond those included in the standard model could resolve some of the SM shortcomings. It can provide a candidate for Dark Matter and a solution to the hierarchy problem. LÄS MER

5. 4. Search for Stop Using the ATLAS Detector and Performance Analysis of the Tile Calorimeter with Muons from W Decays

   Författare :Stefio Yosse Andrean; Christophe Clement; Joakim Edsjö; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; standard model; bsm; supersymmetry; stop; calorimeter; ATLAS; fysik; Physics;

   Sammanfattning : This thesis presents a search for the supersymmetric partner of the top quark in the final state with one lepton. The search focuses especially in the region of the parameter space where the 2-body decay dominates. The analysis is performed using LHC full Run 2 data at √s = 13 TeV as recorded by the ATLAS detector. LÄS MER

7. 5. Development and Test of the ATLAS Tile Calorimeter Digitizer

   Författare :Jonas Lesser; Christian Bohm; Lorne Levinson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Sammanfattning : The new LHC particle accelerator now being built at CERN will have a radically increased event rate and higher energy. To accommodate this, instrumentation for LHC experiments has had to be constructed using new ideas and the latest available technology. LÄS MER
