描述了一种先进的正电子寿命装置，特别适合于对辐照过的核反应堆压力容器钢进行测量。该设备存在三个BaF2探测器在三重符合模式下操作，以避免非常令人不安的60 Co的贡献的寿命谱。BaF2晶体的使用产生了可接受的效率和远低于300 ps的时间分辨率。
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 disturbing60Co-contribution in the lifetime spectra. The use of BaF2scintillators gives rise to an acceptable efficiency and a time resolution well below 300 ps.
