Results of Recent Testing Campaigns of the Analogue Pixel Test Structure — •Maximilian Spors1,2, Malte Grönbeck1,2, Alexander Rachev1,2, Lars Döpper1,2, Philip Hauer1,2, and Bernhard Ketzer1,2 for the ALICE Germany collaboration — 1Helmholtz-Institut für Strahlen- und Kernphysik, Universität Bonn, Germany — 2Forschungs- und Technologiezentrum Detektorphysik
For the Long Shutdown 4 of the LHC, the ALICE Collaboration is planning a major upgrade of its detectors, known as ALICE 3. The tracking system of ALICE 3 will be entirely based on Monolithic Active Pixel Sensors (MAPS), fabricated using TPSCo’s 65 nm CMOS imaging process. Dedicated small-scale Analogue Pixel Test Structures (APTS), originally developed for the Inner Tracking System 3 project, are used to study the analogue response to incident radiation. As this technology is also planned to be used for the ALICE3 tracking system, the APTS measurements provide insights into the characteristics of sensors fabricated in this process, such as detection efficiency, spatial resolution and in-pixel efficiencies.
This presentation summarizes the results of recent testing campaigns, consisting of test beam measurements at ELSA, as well as laboratory experiments using X-ray sources.
