Abstract
For the High-Luminosity upgrade of the Large Hadron Collider, the instantaneous luminosity of the LHC is expected to reach unprecedented values, resulting in about 200 proton-proton interactions in a typical bunch crossing. To cope with the resulting increase in occupancy, bandwidth and radiation damage, the current ATLAS Inner Detector will be replaced by an all-silicon system, the Inner Tracker (ITk). In the outermost part of this tracker is the Strip Detector, which has a highly modular design, with a barrel region and two end-caps. This thesis explores various phases of the ITk project, from prototyping to pre-production, with a particular focus on assembly procedures, performance characterization, and quality control and assurance measurements for the detector components and system employed at Brookhaven National Laboratory. It covers the assembly techniques adopted for assembling hybrids and modules, which have been refined based on feedback from metrology and electrical tests. A detailed examination of the detector system performance, beginning with the setup, procedure, and results of the first fully-instrumented prototype stave developed at BNL, and culminating with the results and challenges encountered during the latest phase, is offered. This thesis will delve into the performance of the pre-production staves and offerinsights into how they have been optimized to achieve the ITk project’s objectives.
