Description
GAMMA-400 space-based gamma-ray telescope represents the core of the scientific complex intended to perform a search for signatures of dark matter in the cosmic gamma-emission, measurements of diffuse gamma-emission characteristics, investigation of extended and point gamma-ray sources, studying of high energy component of gamma-ray bursts and solar flares emission. Prototypes of anticoincidence detector and two calorimeters were tested on synchrotron C-25P «PAKHRA» of Lebedev Physical Institute in Russia. The prototype of anticoincidence detectorconsists of strip of polyvinyltoluene scintillator ВС-408 with dimensions of 1280x100x10 mm3, the prototypes of calorimeters consist of CsI(Tl) crystals with sise of 330x50x20 and 450x36x36 mm3. All detectors prototupes used SiPM readout.The results of measurements of detectors characteristics are discussed in the work presented.
