Summary
Monolithic CMOS sensors (called MAPS, Monolithic Active Pixel Sensors) were invented in the mid-1990s and their great potential as imaging devices was immediately exploited in a wide range of applications.
Since the beginning of the 21st century, MAPS have also been proposed and implemented as high-resolution spatial trackers for particle physics experiments.
This is the case, for example, of the Muon Forward Tracker and Inner Tracking System, two detectors recently built and integrated within the framework of the ALICE experiment’s rejuvenation program at the LHC (CERN).
Full description
The IRFU is currently developing CMOS sensors in L-Foundry technology as part of an international collaboration with a temporal resolution below 100 ps. Several prototypes have already been designed, manufactured, and tested.
Recently, a new prototype featuring several different-sized collection diodes and preamplifiers has been designed and sent for fabrication, incorporating improvements and performance optimizations compared to previous iterations.
The intern will participate in setting up a test bench which they will use for an extensive characterization of this prototype. The measurements will focus on the detector noise characteristics, the temporal resolution characterization of the readout electronics, and the measurement of the effective capacitance of the detection diode.
The results of these studies provide important information for selecting the type of diode and preamplifier architecture that offers the best performance in terms of signal-to-noise ratio and power consumption for future developments.
