  1. 1. Applications of Pulse Shape Analysis Techniques for Segmented Planar Germanium Detectors

    Författare :Anton Khaplanov; Bo Cederwall; Bo Jakobsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Position sensitive detectors; pulse shape analysis; germanium detectors; DESPEC; ; Nuclear physics; Kärnfysik;

    Sammanfattning : The application of pulse shape analysis (PSA) and γ-ray tracking techniques has attracted a great deal of interest in the recent years in fields ranging from nuclear structure studies to medical imaging. These new data analysis methods add position sensitivity as well as directional information for the detected γ-rays to the excellent energy resolution of germanium detectors. LÄS MER

    Sammanfattning : Introduction. Road traffic injuries are the eighth leading cause of death globally and the leading cause of death among young people aged 15-29. Of individuals killed or injured in road traffic injuries, a large group comprises occupants sustaining a thorax injury in frontal crashes. The elderly are particularly at risk, as they are more fragile. LÄS MER
