DISPOSITIF POUR LA VISUALISATION DE DESINTEGRATIONS DE POSITONS.

摘要

The device consists of at least one pair of scintillators (28) sensitive to gamma rays and placed opposite each other, together with sets of photomultipliers (30) each associated with a scintillator. Means (34) are provided for measuring the centroid of the position of the scintillations in the scintillators. Means (36) are provided for determining the time of flight of the gamma rays detected by coincidence in each of the coupled scintillators. Means (38) are provided for locating the decay of the positrons together with a system (40) for displaying the image. …Application to the study of inaccessible organs, whether living or not. ……
