摘要
This work presents the development of a Geiger-mode Avalanche PhotoDiode pixel detector in standard CMOS technologies aimed at the vertex and tracker regions of future linear colliders, i.e. the International Linear Collider and the Compact Linear Collider. In spite of all the advantages that characterize this technology, GAPD detectors suffer from noise pulses that cannot be distinguished from real events and low fill-factors that reduce the detection efficiency. To comply with the specifications imposed by the next generation of particle colliders, solutions to minimize the intrinsic noise pulses and increase the fill-factor have been thoroughly investigated.
