What is DCS?

DCS = Detector Control System

Detector is too complex and it is not possible to operate a detector by a small crew of experts. A Detector has to run without interruption for many years, except in long shutdown periods. In order to make it possible to operate the detector easily, the name "Detector Control System" (DCS) comes into the picture.

DCS system of the GEM GE1/1 station has been developed based on a "Supervisory Control and Data Acquisition" (SCADA) software referred to as "Wincc OA".

DCS Purpose

• Continuous and safe operation of the detectors
• Voltage (HV/LV) controlling and monitoring
• Monitoring of gas system and environmental parameters
• External system communication

The 5 Main Sections of the GEM DCS

• Standard HV + LV control and monitoring
• Finite State Machine (FSM)
• Gas and environmental parameters monitoring
• Radiation monitoring (RadMon)
• LHC, Magnet, DSS, Temperature monitoring
