Development of a new silicon pixel detector with 10 ps time resolution for high luminosity future experiments

In this thesis work the results of the characterizations of the 3D-trench TimeSPOT silicon sensors with minimum ionizing particles are described. Such devices have been developed to satisfy the requirements of the LHCb VErtex LOcator detector for the Upgrade II, planned to face the high luminosity conditions. These requirements are a time resolution better than 50 ps per hit, a spatial resolution of the order of 10–20 μm and a radiation hardness up to 6·10^16 1 MeV n_eq/cm^2. In this thesis the characterizations performed both in the laboratory with a 90Sr source and in several test beam campaigns are illustrated. The main measurements done are the time resolution and the detection efficiency before and after the irradiation up to 2.5·10^16 1 MeV n_eq/cm^2.
