Abstract:
The Munich scanning positron microscope (SPM) permits positron lifetime measurements with a lateral resolution down to 2 um within an energy range of 1-20 keV. One practical limitation of the SPM is set by the long measurement times of several days per a 2D-scan due to the low intensity positron beam produced by standard 22Na sources. This disadvantage will be overcome by installing the SPM at the high intense positron beam facility NEPOMUC at the research reactor FRM II in Garching. Thus the ti... »
