Measurements of the CMS Inner Tracker pixel assemblies for the Phase-2 upgrade — •Bianca Raciti, Massimiliano Antonello, Erika Garutti, Jörn Schwandt, and Georg Steinbrück — University of Hamburg, 22761, Luruper Chaussee 149, Hamburg, Germany

During Long Shutdown 3, the entire CMS Tracking System will be replaced to operate during the High Luminosity LHC running phase with considerably increased luminosity. The new pixel sensors will have to fulfill stringent requirements to operate in an extremely harsh radiation environment and cope with the high data readout rate.

An extensive campaign has taken place to characterize the first half-size pixel chip demonstrator (RD53A), which led to the submission and production of the first full-size prototype chip (RD53B-CMS).

The new sensor-readout chip modules have been extensively tested both in the laboratory and at the CERN and DESY testbeam facilities.

This study presents results on the performances of the two subsequent iterations of pixel assemblies with different irradiation levels, sensor designs and experimental conditions.
