Description

Scintillation characteristics of a mixed CsI-CsBr 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 CsI-CsBr 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 CsI-CsBr and HPMTs is proposed. It is suggested that the CsI-CsBr scintillator may be used in electromagnetic calorimeters at counting rates greater than 107 s-1. (orig.)
