Assembly and Test of Prototype 2S Modules for the Phase-2 Upgrade of the CMS Outer Tracker

<!--HTML-->Within the scope of the High Luminosity LHC upgrade the CMS experiment will be upgraded because due to radiation damage many components cannot be used any longer and higher particle fluxes will raise the technical requirements. In addition to other detector components, the entire silicon strip tracker will be replaced. The new sub-detector will consist of so-called PS and 2S modules with a stacked pair of sensor layers each. This module design will enable the integration of tracking information into the Level-1 trigger of the CMS detector on hardware level.<br>The Physics Institute IB and the Physics Institute IIIB of RWTH Aachen University committed to assemble and test up to one thousand 2S modules. In the course of this PhD thesis multiple prototype detector modules have been assembled and the assembly procedure has been tested and improved with the focus being placed on the wire bonding step. The bonding quality has been evaluated by analyzing the bond machine data. As a tool for the module series production, a user interface has been developed to identify weak bonds. For the reception test of Kapton strips, which are used as high voltage isolators in the module assembly, a test setup with a dedicated user interface has been created. In addition, the series production was prepared by performing a detailed estimation of the assembly time and the required storage capabilities.<br>Prototype modules were also used to test procedures for identifying and repairing damages. The properties of close-to-final prototype modules have been measured at the Test Beam Facility DESY with an electron beam. The particle tracks of the beam telescope have been aligned to the hits on the tested modules and the data have been analyzed. The analysis includes a study of the detector's spacial resolution, the assembly precision and a detailed evaluation of the hit and stub efficiency at different locations of the sensors and under different incidence angles. The results of the beam test analysis are furthermore discussed in the context of the detector operation at the High Luminosity LHC.
