Description
The ATLAS (A Toroidal LHC Apparatus) will undergo modernization between 2026 and 2030 to prepare for operations at the high luminosity regime of the HL-LHC (High-Luminosity Large Hadron Collider). To address the challenging radiation levels, higher data rates, and extremely high-occupancy environment, the ATLAS Inner Detector will be upgraded and replaced with a new all-silicon pixel and strip tracker known as the ITk (Inner Tracker). Simultaneously, a detector control system (DCS) is being developed for the ITk to ensure the proper functioning of each part of the new detector. Patch Panel 2 (PP2) is an active component of the strip tracker's power supply (PS) chain, which will be located inside the ATLAS detector. It will connect two different types of cables within the PS system and convert the 48V voltage delivered from service caverns to the 12V required for the ITk Strip detector structures. An independent readout system is needed to connect to PP2 for safety and control reasons. Currently, the PP2 system is in the pre-production phase. The equipment must undergo detailed Quality Control (QC) checks before being installed in the ITk detector. A dedicated DCS system is being developed to facilitate the automated QC procedure. I will present the PP2 design during its prototype phase, along with its readout system and the plans for the QC of the pre-production PP2 series, which are being developed in Cracow.
