  1. 1. 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

  3. 2. Interfacial Dynamics at Surface Modified Molecular/Perovskite Solar Cells : How measurements are made to understand solar cell stability

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Benjamin Verbeek; [2023]
    Nyckelord :perovskite; solar cell; solar; energy; XPS; synchrotron;

    Sammanfattning : Humanity has great energy demands, and must simultaneously combat climate change by curbing anthropogenic greenhouse gas emissions. Perovskite solar cells (PSC) provide a low-carbon energy source, at lower production costs than traditional silicon-based solar cells. PSC's suffer some issues with long-term stability. LÄS MER

  4. 3. Studies of the J/Ψ → anti-Σ0Σ0 Reaction with BESIII : Event Selection Development

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Benjamin Verbeek; [2023]
    Nyckelord :hyperon; CP; symmetry; event selection; tracks; BES; BESIII; USTC;

    Sammanfattning : The apparent symmetry between matter and antimatter raises the question of why the universe consists of mostly matter. Via an academic exchange to USTC Hefei, a reaction was studied that aims to give insight into this question. LÄS MER

  5. 4. Maximum Likelihood Estimation of Hyperon Parameters in Python : Facilitating Novel Studies of Fundamental Symmetries with Modern Software Tools

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Benjamin Verbeek; [2021]
    Nyckelord :CP-symmetry; maximum log-likelihood; python; estimation; BESIII; PANDA; hyperon; numba;

    Sammanfattning : In this project, an algorithm has been implemented in Python to estimate the parameters describing the production and decay of a spin 1/2 baryon - antibaryon pair. This decay can give clues about a fundamental asymmetry between matter and antimatter. LÄS MER
