  1. 1. The Commissioning of a Pixelated Charge-particle Detector : for High-sensitivity Measurements of Hydrogen

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

    Författare :Joacim Stenlund; Aram Himelius; [2023]
    Nyckelord :;

    Sammanfattning : The Tandem Laboratory at Uppsala University, a national research infrastructure forworld-leading materials analysis, has a long history of performing hydrogen measurementusing NRA (Nuclear Reaction Analysis). This project intents to diversify the infras-tructure for hydrogen measurement by investigating the feasibility of an advanced ERCS(Elastic Recoil Coincidence Scattering) system, enabling finer detection limits.

  3. 2. 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.

  4. 3. Nuclear Structure near the Proton Drip-line: A Search for Excited States in 62Ge

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

    Författare :Dalia Farghaly; [2022]
    Nyckelord :nuclear physics; nuclear structure; proton drip-line; excited states; germanium; fusion-evaporation reaction; experimental nuclear physics; gamma sphere; gamma spectroscopy; HPGe detectors; data analysis; Physics and Astronomy;

    Sammanfattning : An experiment to study mirror symmetry in the mass A = 60 region was performed at the Argonne National Laboratory (ANL) in 2020. The fusion-evaporation reaction 40Ca + 24Mg → 64Ge* at a beam energy of 106 MeV was used to populate excited states in 62Ge. LÄS MER

  5. 4. Dynamic Analysis of Double Tee Floors Subjected to Human Activity : A comparison between a standard- and a modified cross section

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Bjondina Hoti; Fadi Simonides; [2022]
    Nyckelord :;

    Sammanfattning : Building with larger spans and more slender elements is more common today since the demand for open floor plans has increased. The consequence is that low frequency floors and vibration problems arise. Such floors tend to undergo large vibrations since their low eigenfrequency coincides with the frequency which human activities have. LÄS MER

  7. 5. Is Triple Coincidence a Viable Method for Nuclear Weapons Detection in Light of Double Coincidence Methods?

    L3-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Karl Herlin; [2021]
    Nyckelord :Xenon; Coincidence; Nuclear weapons; Monte Carlo; simulation; Double coincidence; Triple cpincidence; isotope;

    Sammanfattning : A fully functioning Comprehensive nuclear-Test-Ban Treaty (CTBT) is essential for a world free of nuclear weapons. To measure radionuclides in the atmosphere in accordance with the CTBT, facilities such as SAUNA uses double coincidence techniques to discriminate between interesting Xenon isotopes. LÄS MER
