This paper presents the design and characteristics of a front-end readout application-specific integrated circuit (ASIC) dedicated to a multichannel-plate photodetector coupled to LYSO scintillating crystals. In our configuration, the crystals are oriented in the axial direction readout on both sides by individual photodetector channels allowing the spatial(More)
CMOS Monolithic Active Pixel Sensors (MAPS) are proposed as a technology for various vertex detectors in nuclear and particle physics. We discuss the mechanisms of ionizing radiation damage on MAPS hosting the the dead time free, so-called self bias pixel. Moreover, we discuss radiation hardened sensor designs which allow operating detectors after exposing(More)

A novel Monolithic Active Pixel Sensor (MAPS) for charged particle tracking is presented. The partially depleted thin epitaxial layer of a low-resistivity silicon wafer is used as a sensitive detector volume from which the charge liberated by ionising particles is collected by diffusion. The sensor is a photodiode within a special structure allowing the(More)
