  1. 1. Defining dark jets at the particle level

    Master-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Gustav Lindberg; [2023]
    Nyckelord :Particle physics; Dark matter; QCD; Physics and Astronomy;

    Sammanfattning : One hypothesis that attempts to explain dark matter is dark QCD, which suggests that there would be a dark sector made up of dark quarks. Dark quarks would interact with each other through dark QCD similar to how Standard Model quarks interact with each other through Standard Model QCD. LÄS MER

  3. 2. Total Monte Carlo of the fission model in GEF and its influence on the nuclear evaporation in TALYS

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Karlsson Peter; [2023]
    Nyckelord :physics; nuclear physics; fission; neutron-induced; evaporation; Hauser-Feshbach; GEF; TALYS; Total Monte Carlo; TMC; fysik; kärnfysik; neutron-inducerad;

    Sammanfattning : Features recently added to the nuclear reaction software TALYS allow the use of the GEF model as a fission fragment generator. GEF generates data for fission fragment yields, total excitation energy (TXE), total kinetic energy (TKE) and individual fragment excitation energies (E*) with their standard deviations through Monte Carlo simulations for TALYS.

  4. 3. Benchmark of the fission channels in TALYS

    Master-uppsats,

    Författare :Fredrik Nordström; [2021]
    Nyckelord :Fission; Prompt neutrons; Prompt gamma-rays; Nuclear reaction codes; TALYS; GEF;

    Sammanfattning : In this project, different fission models in the nuclear reaction code TALYS have been compared to GEF version 2020/1.2. The data included in the comparison are mass yield distributions, average prompt neutron energies per fragment mass, and average multiplicities of both neutrons and γ-rays per fragment mass. LÄS MER

  5. 4. Design, Construction and Characterization of a Portable Fast-Neutron Detector

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

    Författare :Nicholai Mauritzsson; [2017]
    Nyckelord :fast-neutrons; detector; plastic scintillator; NE110; neutron tracking; scintillation; spallation; european spallation source; sonnig; Physics and Astronomy;

    Sammanfattning : At European Spallation Source ERIC, 2 GeV proton bunches will be accelerated towards a tungsten target where spallation will occur, producing a wide neutron energy spectrum. Despite the shielding and moderators in place to stop and/or reduce their energy, a significant portion of the most energetic neutrons, called prompt neutrons, might still reach the sample position of a neutron-scattering instrument.

  7. 5. BNCT in vivo dosimetry A feasibility study using an HPGe detector for prompt gamma spectroscopy

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Carl Östlund; [2005]
    Nyckelord :Strålterapi; Medicine and Health Sciences;

    Sammanfattning : Increased accuracy in patient dosimetry in BNCT is needed. This need for more accurate individual patient dose estimations initiated this project at the Swedish BNCT facility at Studsvik. One possible way to achieve this is to use an HPGe detector. LÄS MER
