Description
For the High Luminosity (HL) upgrade of the Large Hadron Collider (LHC), the current ATLAS Inner Detector will be replaced by an all-silicon Inner Tracker (ITk), consisting of a pixel detector surrounded by a strip detector.
The pixel detector has five barrel layers and a number of rings, resulting in about 13 m^2 of instrumented area that consists of almost 10000 modules.
To minimise material budget, this is the first time a serial powering scheme is deployed to operate a silicon detector on such a scale.
This talk will give an overview of the various components of the pixel system, such as sensors, frontend chips, modules and larger structures, highlighting the design choices, testing results from prototypes, current status and various technical challenges.
