Abstract
The upcoming ATLAS Phase II upgrade mandates replacing the tracking system with the all-silicon Inner Tracker (ITK), featuring a pixel detector as its core element. The monitoring data of the new system will be aggregated from an on-detector ASIC, Monitoring Of Pixel System (MOPS), and channeled to the Detector Control System (DCS) via a newly developed FPGA-based interface known as MOPS-Hub. The mitigation strategies for addressing potential Single-Event Upset (SEU) issues in the new system, along with the proton irradiation results, are presented.
