Study of Geiger avalanche photo-diodes (GAPDs) applications to pixel tracking detectors

摘要

The effort at the UB and CNM to study the feasibility of using standard CMOS technology Geiger avalanche photo-diodes (GAPDs) for pixel tracking detectors is reported. Generally APDs are used as photon detector devices. The possibility of using APDs in Geiger mode (that is reverse-biased above breakdown) for direct particle detection is the purpose of the ongoing R&D program, which tries to exploit GAPDs' features suitable for particle detection.
