    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. Can blue mussel shells be used for retrospective 14C-analysis in the marine environment of nuclear power plants?

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

    Författare :Sofia Bjarheim; [2024]
    Nyckelord :Radionuclide; Marine Environment; Blue Mussels; 14C; Nuclear Power Plant; Physics and Astronomy;

    Sammanfattning : Carbon-14 (14C) is one of the most important contributors to the collective effective dose of the public due to radioactive releases from nuclear power plants. However, the discharge of 14C from nuclear power plants (NPPs) into water has not been measured previously. LÄS MER

  4. 3. Propagation of Nuclear Data Uncertainties for Reactor Physics Parameters in Fluorine-19-based Molten Salt Reactors

    Master-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Sigfrid Stjärnholm; [2023]
    Nyckelord :;

    Sammanfattning : It could be argued that a renaissance is taking place for the global interest in nuclear power - especially for the development of the next generation of reactor systems that aim at solving the problems with contemporary energy production with nuclear technology. One such proposed concept for Gen IV nuclear power is a Molten Salt Reactor (MSR), in which the nuclear fuel is in solution of a salt - often based on fluorine or chlorine. LÄS MER

  5. 4. Combustibility study of resin for warm magnet coils used at CERN

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Juan Carlos Lopez Santiago; [2023]
    Nyckelord :Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

    Sammanfattning : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. LÄS MER

  7. 5. Developments Towards High-Resolution Muonic Atom X-ray Spectroscopy of Low-Z Elements : For precision measurements of absolute nuclear charge radii

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Benjamin Verbeek; [2023]
    Nyckelord :muon physics; subatomic physics; charge radius; nucleus; lithium; silicon drift detector; microcalorimeter;

    Sammanfattning : This Master's thesis investigates a method to measure atomic nuclei with record precision using muonic atom X-ray spectroscopy. In particular, 6Li is measured experimentally. The method used is independent from the previous most precise measurement of the 6Li nuclear charge radius which uses electron scattering. LÄS MER
