摘要：

Scintillation characteristics of a mixed CsICsBr crystal have been studied. The crystal luminescence spectrum is 280-340 nm; the decay time is 11 ns; the relative light yield is 0.18 of NaI(Tl). The parameters of the γ-quantum hodoscope based on CsICsBr and hodoscopic PMTs (HPMTs) have been measured. The hodoscope spatial resolution is shown to be 2σ = 2.4 mm. A design of a positron emission tomograph ring on the basis of CsICsBr and HPMTs is proposed. It is suggested that the CsICsBr scintillator may be used in electromagnetic calorimeters at counting rates greater than 107 s-1. © 1990.
