  1. 1. Derivation of Improved K^0_L Response Uncertainty for use in the Jet Energy Scale Calibration at ATLAS

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikelfysik

    Författare :Alexander Ekman; [2019]
    Nyckelord :kaon; neutral kaon; K^0_L; K_Long; klong; single-particle response; response; detector response; calorimeter; ATLAS; CERN; jets; trigger level analysis; TLA; physics list; Monte Carlo; MC; Physics and Astronomy;

    Sammanfattning : The Standard Model of particle physics (SM) attempts to describe the fundamental particles and how they interact with each other. This model is however incomplete, as shown by various experimental observations. ATLAS is one of the experiments currently in operation at the Large Hadron Collider, which aims to search for new physics beyond the SM. LÄS MER

  2. 2. A Client-Server Solution for Detecting Guns in School Environment using Deep Learning Techniques

    Magister-uppsats, Linköpings universitet/Medie- och InformationsteknikLinköpings universitet/Tekniska fakulteten

    Författare :Johan Olsson; [2019]
    Nyckelord :machine learning; gun detection; tensorflow; server; client; training; school shootings; school environment; gun control; SSD; RetinaNet; transfer learning; AI; surveillance; IP; network; camera; Axis; Communications;

    Sammanfattning : With the progress of deep learning methods the last couple of years, object detection related tasks are improving rapidly. Using object detection for detecting guns in schools remove the need for human supervision and hopefully reduces police response time. LÄS MER

  3. 3. Simulation of Detector Response : How Does the Electron Multiplication Differ Within Ionization Chambers with Various Geometries?

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem; KTH/Medicinteknik och hälsosystem

    Författare :Matilda Messén; Elvira Moser; [2019]
    Nyckelord :nuclear physics; simulation model; ionization chamber; electron multiplication; Python 3.7; inner radius; anode wire radius; electric field strength; multiplication peak;

    Sammanfattning : This degree project was performed in collaboration with the division of nuclear physics at the department of physics, KTH Royal Institute of Technology. A partial goal of the project was to create a simulation model, where the relationship be- tween the multiplication of electrons that occurs in an ionization chamber and the different pressures of air in the detector could be visualized.

  4. 4. Simulation of Anti-Compton Shield Augmentation to the Lundium Decay Station Using Geant4

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Daesung Cho; [2019]
    Nyckelord :Lundium; Geant4; Anti-Compton shield; gamma spectroscopy; Physics and Astronomy;

    Sammanfattning : The Lundium decay station improves on the existing TASISpec spectrometer used to investigate the nuclear structure of superheavy nuclei by photon- and charged particle-spectroscopy. This thesis aims to explore the potential benefits of the future Lundium station with the augmentation of anti-Compton shields com- posed by a set of BGO scintillator bars. LÄS MER

  5. 5. 2D Neutron Imaging with 10B-Based Multi-Blade Detector

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Författare :Tõnu Ilves; [2018]
    Nyckelord :thermal; neutron; imaging; 2D; Multi-Blade; detector; boron; boron-10; nuclear physics; multi wire proportional chamber; digitizer; ESS; European Spallation Source; surface study; reflectometry; Physics and Astronomy;

    Sammanfattning : In the field of thermal-neutron imaging, the Multi-Blade detector concept and design, being developed for the upcoming European Spallation Source in Lund, Sweden, is unique. The current report presents, for the first time, the neutron-imaging capabilities of a boron-10-based Multi-Blade thermal-neutron detector, measured at a reflectometry instrument at Rutherford Appleton Laboratory in Oxfordshire, England under high spallation neutron flux.
