“…Although an unprecedented single-hit timing ∼ 130 ps resolution, able to compete with those of scintillating devices, was achieved by the NA62 collaboration with standard Si-pixel sensors [45,46], this should be considered as a bound performance achievable with conventional planar Si technology. The geometrical layout and technology currently adopted for Si-sensors, in fact, are the limiting factors to obtain better performances for Si-pixel sensors and, most likely, to reach these resolutions for SiMS detectors [47,48].…”
