  1. 11. Characterisation of mechanical and thermal properties of tungsten for high power spallation target applications

    Författare :Jemila Habainy; Materialteknik; []
    Nyckelord :Utmattning; Termisk diffusivitet; Volfram; Spallation; Strålningseffekter; ESS; Oxidation; Mekaniska egenskaper; Mechanical Properties; Thermal diffusivity; Tungsten; ESS; Spallation target; Irradiation effects; Fatigue; Oxidation;

    Sammanfattning : The European Spallation Source (ESS), which is currently under construction in Lund, will use pure tungsten as the spallation neutron target. The tungsten will be irradiated by a 2 GeV proton beam, pulsed at a repetition rate of 14 Hz. LÄS MER

  3. 12. Influence of metallic fission products and self irradiation on the rate of spent nuclear fuel-matrix dissolution

    Författare :Sara Nilsson; Mats Jonsson; István Furó; Göran Lindbergh; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear chemistry; Kärnkemi;

    Sammanfattning : Denna licentiatavhandling behandlar effekten av två inneboende egenskaper (fissions produkter och egenbestrålning) hos utbränt kärnbränsle på hastigheten för strålningsinducerad upplösning av bränslematris (UO2). I ett framtida djupförvar kommer det utbrända kärnbränslet att deponeras 500 meter ner i berggrunden i en reducerande miljö. LÄS MER

    Sammanfattning : This thesis investigates the response of Gallium Arsenide (GaAs) detectors to ionizing irradiation. Detectors based on π-υ junction formed by deep level centers doping. LÄS MER

  5. 14. Tumour targeting with stable and radioactive nuclides : Dosimetric aspects at the cellular level

    Författare :Torbjörn Hartman; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi; Oncology; Onkologi; Biomedical Radiation Science; biomedicinsk strålningsvetenskap;

    Sammanfattning : Targeting with radioactive nuclides or nuclides that can be activated by neutrons may be a powerful tool for treatment of invasive tumours and disseminated tumour cells. The targeting agents are designed to find tumour cells and deliver the nuclides. LÄS MER

  7. 15. Investigation of GaAs structures for microstrip detectors

    Författare :Valery Chmill; KTH; []
    Nyckelord :;

    Sammanfattning : The performance of Gallium Arsenide p-i-n detectors afterneutron irradiation has been studied. The detectors have beenirradiated with » 6 MeV neutrons at various neutronfluences up to approximately 6 ¢ 1014 n/cm2, protons andmixed beam up to 1015 p/cm2. LÄS MER
