The Design Of Besiii Cgem Detector Control System

This paper reports the Detector Control System (DCS) of a Cylindrical Gas Electron Multiplier (CGEM) detector, which is the upgrade of the inner tracker detector of BESIII. A dedicated powerful online DCS is required to ensure the safety and correct operation of the CGEM system, which is distributed on several subsystems, including low and high voltage power supplies, front-end electronics, environmental sensors, gas and cooling infrastructure. This paper presents the hardware architecture and software solutions adopted and the evolution along with the results in commissioning phase in the laboratory will also be discussed.
