Radiation Imaging and Tracking (GRIT)
The Group for Radiation Imaging and Tracking designs and develops advanced solid-state detectors aimed at recording different kind of radiations at different energies, like visible light photons, x-rays photons, low momentum (1-100 keV) electrons, energetic hadrons (MIPS), and others. Radiation detectors find use in a wide range of applications, ranging from High Energy Physics experiments to space-borne observatories, including both industrial and medical equipment and systems.
The DFA Group for Radiation Imaging and Tracking (GRIT) actively moves the latest developments in solid-state detectors and systems designed for High Energy Physics and Space experiments to applied fields, like the medical and industrial one.

Research activities
Depleted Monolithic Active Pixel Sensors
R&D on Depleted Monolithic Active Pixel Sensors (D-MAPS) for next generation particle colliders (ALICE collaboration, EIC, FCC, Muon Collider). Monolithic pixel sensors embed within a very thin silicon layer (few tens microns) both the sensor and the readout and processing electronics, rendering them very lightweight devices ideal for particles detection where minimum material budget and high power efficiency are mandatory.
Other than High Energy Physics, space and medical application, such sensors have extensive use in other fields, such as Electron Microscopy, X-Ray crystallography, NIR and UV imaging, LIDAR applications, Time of Flight measurements, etc.

X_rays imaging
Use of monolithic detectors in industrial and medical X-Rays imaging systems. While both industrial and medical X-Rays apparatuses rely on high-Z materials (Germanium, CdTe, etc..) to achieve high efficiency on soft to medium energy X-Rays (1 keV to 100 keV), modern developments of microelectronic technology makes it feasible to use simple silicon for X-Ray detection up to these energy, while providing superior performances in term of speed and cost.

Radiation hardness
Radiation hardness characterization of circuits and devices. Microelectronic circuits and devices cannot operate in radiation environments like those found in high energy physics experiments, space applications, and even some medical facilities, without proper hardening and/or modifications. Investigating how microelectronic sensors and devices degrade their performance, up to failure, and understanding how to mitigate such issues to make them suitable for scientific applications represents a relevant part of the R&D effort.
