Abstract:
The ITS3 upgrade of the ALICE experiment at the LHC introduces curved, ultra-thin silicon sensors in cylindrical geometries, reducing material and enhancing tracking. A key innovation is the use of a 65 nm CMOS technology. This thesis focuses on the characterisation, as well as simulations studies, of a 65 nm prototype through lab and beam tests, analysing charge collection, efficiency, and radiation tolerance. Findings validate the technology for ITS3 and future high-energy physics applications.

Die ITS3-Aufrüstung des ALICE-Experiments am LHC nutzt gebogene, ultradünne Siliziumsensoren in zylindrischer Geometrie, um Material zu reduzieren und das Tracking zu verbessern. Eine Schlüsselinnovation ist die 65-nm-CMOS-Technologie. Diese Arbeit behandelt die Charakterisierung und Simulation eines 65-nm-Prototyps durch Labor- und Strahltests, mit Analysen zu Ladungssammlung, Effizienz und Strahlenresistenz. Ergebnisse bestätigen die Eignung der Technologie für ITS3 und zukünftige Anwendungen.
