  1. 1. Decay Chains of Fast Alpha Emitters in the Actinide Region

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

    Författare :Tanvir Sayed; [2024]
    Nyckelord :alpha decay; alpha emissions; fine structure; decay chain; decay scheme; alpha spectrometry; actinide; nucleus; nuclear structure; nuclear states; energy levels; uranium isotopes; U310 experiment; parasitic runs; decay station; TASISpec ; moving window deconvolution; digitisers; alpha-gamma coincidence; 221-Th decay; fine structure of alpha decay to 217-Ra; GSI; Gamow s theory; Geiger-Nuttall; chain search; short half-lives; Physics and Astronomy;

    Sammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER

  3. 2. 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.

  4. 3. 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

  5. 4. PERFORMANCE OF THE PHOTODETECTOR FOR THE ACTIVE SHIELD OF THE COSI SPACE TELESCOPE
