A PARTICLE DETECTOR CAPABLE OF SEPARATING IN-TIME SIGNALS FROM OUT-OF-TIME SIGNALS

摘要

Silicon Particle Detector, comprising an absorption region (10) capable of generating electrical charges in response to a particle passing therethrough, a first and a second electrode (20, 30) arranged on opposite sides of the absorption region (10), wherein the first electrode (20) is segmented into a plurality of pads (20a), and a plurality of multiplication layers (40) able to avalanche-multiply the electric charges generated in the absorption region (10), each of the multiplication layers (40) being arranged beneath a respective pad (20a) and interposed between it and the absorption region (10), each multiplication layer (40) is surrounded by a respective protection ring ( 50) formed by the material of the pad (20a). The protection ring (50) is laterally interposed between the multiplication layer (40) and the absorption region (10).
