摘要：
The author reports on the design of a fast coincidence positron lifetime spectrometer, which is based on single crystal barium fluoride (BaF//2) scintillators. A good time resolution (190 ps, FWHM), combined with a high efficiency, has been obtained in the normal experimental set-up (with cathode earthed in the photo multipliers). The pile-up effect is observed to disturb the measured lifetimes in the 180 degree geometry due to the high detection efficiency of the BaF//2 scintillator.
