  1. 1. Development of Radon Detectors for Earthquake Prediction

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Alma Partos; Astrid Schöldström; [2023]
    Nyckelord :Radon; earthquake; gamma ray spectroscopy;

    Sammanfattning : The purpose of this project is to simulate the detection of γ-ray spectra emitted by radon isotopes and their daughters. This is done as a contribution to the development of radiation detectors to be used in a research project investigating the possibility of using increased amounts of the radioactive gas radon as an earthquake precursor.

  3. 2. Prototyping of an automated cyclic Neutron Activation Analysis setup

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

    Författare :Cornelius Maurer; [2022]
    Nyckelord :Nuclear Physics; Neutron activation analysis; cyclic-NAA; Physics and Astronomy;

    Sammanfattning : A prototype Neutron Activation Analysis (NAA) setup based on a Deuterium-Tritium (DT) neutron generator is under development at Lund University. It serves as proof-of-principle for NAA based on a Compact Accelerator-driven Neutron Source. LÄS MER

  4. 3. Measuring the [C II]-to-H I connection in high-redshift absorption-selected galaxies

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Gaurav Senthil Kumar; [2022]
    Nyckelord :QSO; Quasar; Black Hole; AGN; Active Galactic Nuclei; DLA; Damped Lyman Alpha; C II; [C II]; H I; Sightline; HST; X-shooter; Spectroscopy; Echelle Spectroscope; Hyperfine transition; Hyperfine; Physics and Astronomy;

    Sammanfattning : HI neutral gas is the basic building block of galaxies. It dictates the star formation rate and hence the metal enrichment rates within high redshift galaxies. HI neutral gas cannot be directly observed beyond z ≈ 0. LÄS MER

  5. 4. Characterization of a Bismuth germanate Anti-Compton Scattering Shield for use with a Germanium COMPEX detector module

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

    Författare :Samuel Dawes; [2022]
    Nyckelord :COMPEX; Lundium; BGO; ACS; gamma-ray spectroscopy; Physics and Astronomy;

    Sammanfattning : The scope of this work is to help determine the functional improvement brought on by introducing a Bismuth germanate (BGO) Anti-Compton Scattering (ACS) shield system to a germanium COMPEX detector module. The COMPEX germanium detector module is already an extremely useful addition in examining gamma-ray spectroscopy. LÄS MER

  7. 5. Dating lake bottom sediment by searching for 210Pb using gamma-ray spectroscopy

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :William Bäckström; [2020]
    Nyckelord :sediment dating; dating; spectroscopy; gamma-ray; nuclear; lead; HPGe detector; sedimentation; sedimentation rate; attenuation; migration; limnologist; least squares;

    Sammanfattning : In a collaboration with limnologists at Uppsala University a planar HPGe detector has been used to find 210Pb in lake bottom sediment in hopes of getting an estimation for the sedimentation rate. Using a least squares fit to the data, the sedimentation rate was calculated to 0.08 ± 0. LÄS MER
