Particle physics and solid-state Si detectors: HL-LHC from strip sensor to the first bent MAPS

From their beginnings in the 1980s to the present days, solid-state silicon detectors have played a crucial role in particle physics and, in particular, in the field of particle tracking devices. Over the years, different sensor types have been developed. Nowadays, cutting-edge technologies are strip sensors, hybrid pixels, and monolithic active pixels sensors (MAPS). All of these technologies will be used in the upcoming High Luminosity Large Hadron Collider (HL-LHC), a challenging LHC upgrade project designed to increase the current luminosity of the collider. The goal is to provide an integrated luminosity of 3000 $fb^{-1} $ in 12 years, a tenfold increase over the nominal design value of the LHC in its original configuration. This work addresses all the mentioned solid state silicon detector technologies with an historical perspective, going from strips to one of the latest forward-thinking developments, i.e., bent MAPS. For each technology, a R&D project is shown in the context of the HL-LHC. The remarkable outgoing results from these R&D projects are: the characterization of a first strip detector prototype that will be used for the High Luminosity CMS Tracker; the first slow neutron measurement with Medipix3RX technology in the CMS cavern; and finally, the investigation of the first curved solid-state silicon detector, i.e., bent MAPS chips.
