Integrated Control Systems for the Silicon Tracking System of the CBM experiment — •David Gutierrez Menendez for the CBM collaboration — GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, Germany — Goethe-Universität Frankfurt, Frankfurt, Germany

The Silicon Tracking System (STS) is the central detector for charged-particle tracking in the Compressed Baryonic Matter (CBM) experiment at FAIR. Its performance relies not only on the precise operation of 1.8 million readout channels but also on robust Detector Control Systems (DCS) and Experiment Control Systems (ECS) to ensure safe, stable, and automated detector operation. The team previously carried out initial validation of control functionality in the mini-CBM setup. It exercised key components of the STS slow controls, readout supervision, and interlock logic under realistic beam conditions.

Building on these results, dedicated developments and extensive testing have been conducted in a large-scale lab setup to deploy a complete control infrastructure for the assembly and integration of the STS half-units, including monitoring, configuration, and finite-state-machine control for front-end electronics, power systems, and environmental sensors. This lab campaign also serves as a testbed for integrating DCS and ECS workflows ahead of installation at FAIR.

The current status of the STS control systems, together with recent progress and upcoming integration steps, will be presented.
