    Absolute efficiency measurements with the 10B based Jalousie detector

    No full text
    The 10B based Jalousie detector is a replacement for 3He counter tubes, which are not affordable any more for large area detectors due to the 3He crisis. In this paper we will show absolute detection efficiency measurements, conducted at the HEiDi instrument at the FRM II in Munich, which prove that the predicted efficiency can be achieved. This validates the detector concept and its adoption in the POWTEX instrument
