System Integration of ATLAS ITK Pixel DCS ASICs — •Ahmed Qamesh for the ATLAS collaboration — University of Wuppertal

During the LHC phase II shutdown, the entire tracking system of the ATLAS experiment will be replaced by an all-silicon detector called the ITk (Inner Tracker). with a pixel detector as the most inner part. Therefore a new DCS (Detector Control System) is being developed at the University of Wuppertal to fulfill the control and monitoring requirements of the new pixel detector. The new DCS has an on-detector component DCS ASIC to monitor the voltages and temperatures of the sub-detector components. For the communication between the off-detector DCS server and the DCS ASIC a modified CAN (Controller Area Network) bus is used. The powering scheme of the ASICs is supported by direct power lines from the power supplies . In this talk testing results for the proposed communication system (CAN) and Integration plans of the new chip will be presented.
