System Integration of ATLAS ITK Pixel DCS ASICs

Abstract

During the ATLAS phase II upgrade, the tracking system of the ATLAS experiment will be replaced by an all-silicon detector called the inner tracker (ITK) with a pixel detector as the most inner part. The monitoring data of the new system will be aggregated from an on-detector ASIC called Monitoring Of Pixel System (MOPS) and sent to the Detector Control System(DCS) using a new interface called MOPS-HUB. The hardware components of the MOPS-HUB, firmware specifications for the FPGA of MOPS-HUB and its integration plan will be presented. In addition, an irradiation plan for the new system will be introduced.
