  1. 1. Silicon Tracking and a Search for Long-lived Particles

    Författare :Rebecca Carney; Samuel Silverstein; Sara Strandberg; Maurice Garcia-Sciveres; Joel Goldstein; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; silicon; silicon tracking; radiation damage; neuromorphic; neuromorphic computing; long-lived particles; susy; rpvll; displaced vertices; pixel; pixel detector; fysik; Physics;

    Sammanfattning : The ATLAS Detector, below the surface of the Swiss-French border, measures the remnants of high-energy proton-proton collisions, accelerated by the Large Hadron Collider (LHC) at CERN. Recently the LHC paused operations, having delivered an integrated luminosity corresponding to 150 fb−1 of data at a centre-of-mass energy of 13 TeV. LÄS MER

  3. 2. Impact of Ionizing Radiation on 4H-SiC Devices

    Författare :Muhammad Usman; Anders Hallén; Einar Örn Sveinbjörnsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon carbide; ionizing radiation; bipolar junction transistors; reliability; surface passivation; high-k dielectrics; MIS; radiation hardness;

    Sammanfattning : Electronic components, based on current semiconductor technologies and operating in radiation rich environments, suffer degradation of their performance as a result of radiation exposure. Silicon carbide (SiC) provides an alternate solution as a radiation hard material, because of its wide bandgap and higher atomic displacement energies, for devices intended for radiation environment applications.

  5. 4. Instrumentation for silicon tracking at the HL-LHC

    Författare :Rebecca Carney; Samuel Silverstein; Sara Strandberg; Thomas Schön; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Instrumentation; physics; particle physics; atlas; radiation damage; neuromorphic; kalman filter; fysik; Physics;

    Sammanfattning : In 2027 the Large Hadron Collider (LHC) at CERN will enter a high luminosity phase, deliver- ing 3000 fb 1 over the course of ten years. The High Luminosity LHC (HL-LHC) will increase the instantaneous luminosity delivered by a factor of 5 compared to the current operation pe- riod. LÄS MER

  7. 5. Measurements of the Top Quark Pair Production Cross Section and an Estimate of the DØ Silicon Detector Lifetime

    Författare :Sara Strandberg; Christophe Clément; Barbro Åsman; Steinar Stapnes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; particle physics; top quark pair production cross section; silicon radiation damage; DØ detector; Tevatron accelerator; Elementary particle physics; Elementarpartikelfysik; Physics; fysik;

    Sammanfattning : This thesis presents two measurements of the top quark pair production cross section at sqrt{s} = 1.96 TeV using data from the DØ experiment. Both measurements are performed in the dilepton final state and make use of secondary vertex b-tagging. LÄS MER
