  1. 1. Measuring the vertical muon intensity with the ALTO prototype at Linnaeus University

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Magnus Norén; [2021]
    Keywords : Muon Intensity; ALTO; CoMET; Cosmic Rays; VHE Gamma Rays; Extensive Air Shower; Water Cherenkov Detector; Scintillation Detector; Monte Carlo Simulation; GEANT4;

    Abstract : ALTO is a project, currently in the research and development phase, with the goal of constructing a Very High Energy (VHE) gamma-ray observatory in the southern hemisphere. It will detect the particle content reaching the ground from the interactions of either VHE gamma rays or cosmic rays in the atmosphere known as extensive air showers. READ MORE

  2. 2. Calibration of a Fast Neutron Time-of-Flight System

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Armando Javier Morales Urrutia; [2021]
    Keywords : Physics and Astronomy;

    Abstract : Future experiments with thermal neutrons at neutron facilities may encounter fast neutrons as sources of background. Understanding fast neutron behavior on an event-by-event basis in a detector is important for these complementary thermal neutron experiments. One way to study fast neutron events is by performing a time-of-flight measurement. READ MORE

  3. 3. Detections of nuclear explosions by triple coincidence

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Marielle Akser; [2021]
    Keywords : Nuclear explosion; Radioxenon; Comprehensive Nuclear-Test-Ban Treaty; Triple coincidence; SAUNA;

    Abstract : When a nuclear explosion occurs certain radionuclides are emitted, notably xenon. Due to the fact that xenon is a noble gas, it is hard to contain and can therefore be detected far from the explosion site. There are four isotopes of xenon that are of interest in the detection of a nuclear explosion: 131mXe, 133mXe, 133Xe and 135Xe. READ MORE

  4. 4. A gamma-ray study of a highly variable blazar : The Fermi-LAT analysis and the modeling of the FSRQ PKS 1510–089

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Nadja Bollström; [2021]
    Keywords : active galactic nuclei; AGN; astrophysics; jet; PKS 1510-089; Fermi; external Compton model; gamma-rays;

    Abstract : The subject of this thesis is the analysis and modeling of the active galactic nucleus PKS 1510-089. The aim is to present a thorough background of active galactic nuclei combined with the analysis and modeling of a specific active galactic nucleus. The results will then be  linked to previous research and theories about active galactic nuclei. READ MORE

  5. 5. Development of a Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Josephine Lindsey-Clark; [2021]
    Keywords : Neutron Activation Analysis; NAA; European Spallation Source; ESS; Lund Ion Beam Analysis Facility; LIBAF; Gamma-Ray Spectra; Physics and Astronomy;

    Abstract : This report outlines the first stages of the development of the Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility in the Division of Nuclear Physics, Lund University. The motivation for this project is to use the Neutron Activation Analysis detection technique for environmental monitoring around the European Spallation Source, soon to come into operation. READ MORE
