    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

    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

  4. 3. 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.

  5. 4. Strålskydd för nuklearmedicinsk personal som arbetar med 99mTc : Är engångshandskar tillförlitliga vid hantering av radioaktiva lösningar?

    Kandidat-uppsats, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Isabelle Paulsson; [2023]
    Nyckelord :engångshandskar; konversionselektroner; strålskydd; stråldos; teknetium-99m;

    Sammanfattning : Användandet av joniserande strålning i sjukhusmiljöer ökar, vilket leder till enökad stråldos för patienter och personal. Joniserande strålning ärelektromagnetisk- eller partikelstrålning som sänds ut från instabila atomkärnor. LÄS MER

  7. 5. 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.
