Electrical Testing of RD53A Pixel Modules for the Inner Tracker Pixel Detector

The High Luminosity Large Hadron Collider will operate 13.6Tev and will have expected dose of 2·1016 neq/cm2. This upgrade will allow for increased proton-proton collisions at higher energies. The detectors around the LHC will need to upgrade their current sensors to account for increased event density and radiation levels. In the ATLAS detector, the innermost detector, the Inner Tracker(ITk) upgrade will replace the Inner detector and must trace events with the greatest density and highest radiation explosure. In this poster we examine the performance of the RD53A chip, a prototype to the ITk Pixel chip. This chip, along with the entire pixel module have been texted during various phases of assembly before it is assembled on a demonstrator unit. The pixel modules have been tested electrically to determine the quality of its bump bonds, silicon sensor performance, compatibility with its custom readout software, and noise distribution. Current progress has shown promising performance for 14 different modules that have been tested.
