ALICE ITS Upgrade for LHC Run 3: Commissioning in the Laboratory
Abstract
ALICE is the CERN LHC experiment optimised for the study of the strongly interacting matter produced in heavy-ion collisions and devoted to the characterisation of the quark-gluon plasma. To achieve the physics program for LHC Run 3, a major upgrade of the experimental apparatus is ongoing. A key element of the upgrade is the substitution of the Inner Tracking System (ITS) with a completely new silicon-based detector (ITS 2) whose features will allow the reconstruction of rare physics channels not accessible with the previous layout. The enabling technology for such a performance boost is the adoption of custom-designed CMOS Monolithic Active Pixel Sensor as detecting elements. In this proceedings, an overview of the adopted technologies as well as the status of the detector commissioning will be given.
