Abstract

The design is described and the main measurement results are reported for a prototype of a high-energy event registration system of a gamma-ray space telescope on the positron beam of the S‑25R Pakhra synchrotron, Lebedev Physical Institute of the Russian Academy of Sciences. The prototype includes anticoincidence and time-of-flight systems, a pre-shower detector, and a calorimeter based on BC-408, BGO, and CsI(Tl) scintillators with the corresponding front-end and processing electronics units. Silicon photomultiplier matrices are used as photo sensors of all scintillation detectors of the prototype.
