Abstract

The Experiment Control System (ECS) of the LHCb Silicon Tracker sub-detectors is built on the integrated LHCb ECS framework. Although all LHCb sub-detectors use the same framework and follow the same guidelines, the Silicon Tracker control system uses some interesting additional features for operation and monitoring. The main details are described in this document. Since its design, the Silicon Tracker control system has been continuously evolving in a quite disorganized way. Some major maintenance activities are required in order to keep improving it. A description of those activities can also be found here.

Highlights

  • The LHCb [2] experiment control system follows a very clear integrated architecture [3] which was defined early in the implementation process

  • The coding process was driven by the need to test the hardware of the detector

  • The temperature and humidity conditions of the silicon sensors are not monitored by the Detector Safety System (DSS), because no suitable sensors were found. This is why, in the case of the Silicon Tracker, an additional safety level was introduced in the shape of a dedicated Safety Finite State Machine (FSM)
