Development of a Detector Control System for the ATLAS High Granularity Timing Detector — •Davide Caforio, Michael Düren, and Hasko Stenzel — II. Physikalisches Institut, Justus-Liebig-Universität Gießen, Heinrich-Buff-Ring 16, 35392 Gießen

The high-luminosity phase of the LHC will require important upgrades of the ATLAS detector. The experimental challenges are related to the high mean number of interactions per bunch crossing (µ ≈ 200) and the harsh radiation environment. The High Granularity Timing Detector will be able to mitigate the impact from pile-up by an improved track-to-vertex association using a timing measurement with about 30ps resolution. In order to ensure an efficient and safe operation, a detector control system is designed. All relevant detector parameters are continuously monitored and archived for debugging and performance studies, and a system of alert handles signals of abnormal behavior. Interfaces with DAQ, trigger and the accelerator, with interlock signal in case of critical situations, must also be implemented. The large number of read-out channels, the severe environmental conditions characterized by high radiation levels and magnetic fields, the limited space, and the required fast response time of the system are the main challenges faced by the HGTD DCS system.
