Data Acquisition Software for CBM-TOF Super Module Quality Control

The time-of-flight system in the Compressed Baryonic Matter experiment is composed of super modules that are based on multigap resistive plate chambers for high-density and high-resolution time measurement. To evaluate the quality of detectors during mass production, a distributed data readout system was developed. Furthermore, a related data acquisition (DAQ) software was developed under Linux operating system to test and verify the feasibility of the utilized distributed data readout method. In this paper, the DAQ software focused on data collection, event building, status monitoring, and system control. Laboratory tests confirmed the function of the DAQ software for super module quality control and showed that the overall data transfer rate of a single data transmission path can reach up to ~550 Mb/s.
