Abstract
An advanced positron lifetime setup is described, particularly suited to perform measurements on irradiated nuclear reactor pressure vessel steel. The equipment exists of three BaF2-detectors operated in triple coincidence mode to avoid the very disturbing Co-60-contribution in t he lifetime spectra. The use of BaF2 scintillators gives rise to an ac ceptable efficiency and a time resolution well below 300 ps.
