Performance of High Energy Physics Detectors
The subject of my activity has been the characterization, through the development of innovative methodologies and instruments, and design and
optimization of different flavors of pixel sensors, read-out by standard CMOS technology, either as a separate chip than integrated on the same silicon
substrate of the sensing element, for the detection of different types of ionizing radiation.
Several classes of sensors have thus been studied, from the well known Hybrid Pixel Detectors, to the CMOS Active Pixel Sensors, to the modern many-tiers pixel
detectors developed using a 3D Vertical Scale Integration technology.
Complex test setups have been developed as well as dedicated algorithms to extract the important parameters of each sensor.
A modified grazing angle method with medium energy charged particle beams (i.e. few hundreds MeV electrons) has been developed to probe deeply the sensor
