| 520 | _ | _ | |a Modern particle physics is extremely reliant on advanced instrumentation, in particular, detectors. One of the key technologies for current and future experiments is semiconductor detectors. As experiments require higher and higher performance of detectors, continuous R&D is necessary to refine designs and improve performance. The present thesis encompasses diverse R&D efforts on novel silicon detectors and discusses particular detector testing methods, with the two main research directions being developments of sensor characterization techniques by the means of pulsed lasers, and developments for the Phase-2 upgrade of the CMS experiment at the LHC.The first part of the thesis is devoted to the laser techniques. The commissioning and upgrade of the Laserbox, an experimental setup for testing silicon sensors via charge injection with pulsed lasers, is presented. Furthermore, an approach for Monte-Carlo simulations of such laser injection experiments was developed using the Allpix$^2$ framework. These simulations were then validated by a comparison with the experimental data, obtained with the Laserbox. It was shown that the simulation is capable of accurately reproducing signal shapes, induced in silicon sensors in these experimental conditions.The Laserbox was also used to study the DESY digital silicon photomultiplier (dSiPM) prototype, a novel monolithic pixelated photo-detector with CMOS SPADs as sensitive cells. A characterization campaign centering on timing features of the device was conducted. The time resolution of the dSiPM was found to be 53$\pm4$ ps under optimal conditions. Meanwhile, the localized charge deposition with the laser allows one to resolve micrometer-scale features of the tested device, which revealed in-pixel variations of the dSiPM characteristics linked to the pixel cell layout. The second part of the thesis covers the CMS Upgrade, discussing two particular aspects of production and testing of PS modules for the CMS Phase-2 Outer Tracker. First, the development of mechanical construction procedures for the modules and establishment of the robot-assisted assembly pipeline are discussed. These procedures achieve a micrometer-level precision during the assembly, which is crucial for the functioning of the novel $p_t$-discrimination feature of these modules. Second, a qualification campaign for the modules at the DESY II test beam facility is reported, with a focus on detection and $p_t$-discrimination efficiency. It was shown that the module is able to select tracks with a specified $p_t$ at an efficiency of 98$\pm$0.2%, whereas outside the selection region this efficiency drops to below 1%. This campaign proves the production readiness of the module design from the particle detection functionality point of view. |
