Development of the Detector Control System for the ATLAS ITk-Pixel Demonstrator — •Andrés Melo, Jason Veatch, and Stan Lai — II. Physikaliches Institut, Georg-August-Universität Göttingen

The High-Luminosity LHC Upgrade will allow the ATLAS experiment to collect an order of magnitude more data than Run 3. Since the new Inner Tracker (ITk) must cope with this increased occupancy, bandwidth and radiation damage, a sophisticated prototype, called the ITk-Demonstrator, has been built. The ITk-Demonstrator allows the investigation and proof-of-principle for the ITk to be established, with powering, data acquisition, and the Detector Control System (DCS) to be tested in detail.

This talk discusses the tests of the DCS system planned for the ITk and tested with the Demonstrator. Among the technical issues tested were CANMoPs, a package that communicates with a CAN protocol interface, and the serial power protection chips (PSPP) of the Demonstrator. Furthermore, the user interface of the power supply (Wiener PL512) is being redesigned. Among other things, a migration from the Siemens program WinCC for supervisory control and data acquisition from version 3.15 to 3.16 was investigated. This allows the program to run on a Linux operating system, removing the dependence on MS Windows.
