  1. 11. Polymer gel dosimetry with MRI-readout for 3D dose verification - detector characteristics and clinical applications

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Thi Guldhill; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background & Purpose: Radiation therapy is an essential treatment for cancer patients with the ultimate goal to deliver radiation doses to the tumour with precision while minimizing exposure to surrounding healthy tissues. Treatment verification is crucial to ensure the accuracy of radiation delivery, for instance by measuring the radiation dose distribution. LÄS MER

  3. 12. Calibration and preparation of the data analysis of the DORN experiment on board the Chang'E 6 lunar mission.

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Íñigo de Loyola Chacartegui Rojo; [2023]
    Nyckelord :Radon; lunar mission; alpha spectrometry; space instrumentation; performance testing and validation;

    Sammanfattning : As part of the first agreement between the French (CNES) and the Chinese (CNSA) space agencies in terms of space exploration, the DORN instrument will fly on board the Chinese Chang'E 6 mission in 2024. It aims to measure the amount of Radon escaping from the lunar soil to better understand what governs the concentration of this noble gas which contributes to the endogenous origin of the lunar exosphere.

  4. 13. Neutron Veto Inefficiency Studies with FLUKA for the LDMX Hadronic Calorimeter

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

    Författare :Jaida Raffelsberger; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter".

  5. 14. Silicon Drift Detector Simulations for Energy-Dispersive X-ray Spectroscopy in Scanning Electron Microscopy

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Sebbe Blokhuizen; [2023]
    Nyckelord :X-ray spectroscopy; Silicon drift detector; Scanning Electron Microscopy; Detector Simulation;

    Sammanfattning : Scanning Electron Microscopy combined with Energy Dispersive X-ray Spectroscopy (SEM-EDS) is a widely applied elemental microanalysis method. The integration of silicon drift detectors (SDDs) has notably enhanced EDS performance, enabling precise elemental identification due to its large sensitive area and low output capacitance. LÄS MER

  7. 15. Optimization of Gammasphere Data Following the Nuclear Reaction 36Ar + 24Mg → 60Zn∗

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

    Författare :Paul Böhm; [2023]
    Nyckelord :re-calibration; Gammasphere; 54Fe; Physics and Astronomy;

    Sammanfattning : The experiment at Argonne National Laboratory aimed to study the fusion-evaporation reaction following the collision of a high-energy particle beam of 36Ar with a stationary target of 24Mg. This paper outlines the creation and implementation of an automated re-calibration procedure for the high-purity Germanium detectors comprising the Gammasphere array used for γ-ray spectroscopy in this experiment.
