Position-sensitive gamma-ray detector

摘要

ESSAY; Position sensitive gamma-ray detector; The invention relates to a scintillation detector for gamma radiation and can be used both independently and as part of complex tools for search and localization of gamma-ray sources, and to develop the bulk of radiation maps using ground and space together with an unmanned aircraft or helicopter embodiment. Scintillation position-sensitive detector gamma radiation, comprising scintillation crystals, in the form of narrow cylinders or parallelepipeds, arranged in groups along the spherical surface forming the detector boundaries, so that the outer located farther from the detector center, face each scintillation crystal located in a plane tangent to the spherical surface forming the boundaries of the detector, and the central axis of the crystal is directed radially toward the center of the spherical surface.; Furthermore, the crystals are grouped. Each group is located in a plane passing through the center of the spherical surface constituting the boundary detector, the central axis of the crystals of one group are also located in this plane. Internal, located closer to the center of the detector, the surface of each crystal optically articulated with its own photodetector. In use as a photodetector silicon photomultipliers.
