原始语种摘要: Abstract(#br)In this paper we present a position-sensitive detector based on the vertical integration of pairs of aligned pixels operating in Geiger-mode regime and designed for charged particle detection. This novel device exploits the coincidence between two simultaneous avalanche events to discriminate between particle-triggered detections and dark counts. This concept allows to have a reduced material budget and low power consumption in spite of a high granularity and fast timing response. A proof-of-principle prototype was designed and fabricated in a 150 nm CMOS process and vertically integrated through bump bonding. This first demonstrator has been characterized and tested with a high energy particle beams at CERN SPS/PS facilities, in different configurations, featuring a...
