摘要:

压缩重子物质(CBM)实验中的飞行时间(TOF)系统是由多间隙电阻板室(MRPC)组成的超级模块,用于高密度、高分辨率的时间测量。为了在大批量生产过程中对探测器的质量进行评估,开发了满足6.4Gbps高数据速率的分布式数据读出系统,并在Linux操作系统下实现了相应的数据采集(DAQ)软件,验证了分布式数据读出方法的可行性。本文重点介绍了数据采集、事件生成、状态监测和系统控制等模块的设计。实验室测试证实了数据采集软件的功能,单路数据传输速率可达550Mbps左右,满足了需求。

英文摘要:

The time-of-flight (TOF) system in the Compressed Baryonic Matter (CBM) experiment is composed of super modules based on multi-gap Resistive Plate Chambers (MRPC) for high-denseness, high-resolution time measurement. In order to evaluate the quality of detectors during the mass production, a distributed data readout system is developed to meet with the high data rate of 6.4Gbps, and a related data acquisition (DAQ) software is implemented under Linux operating system to test and verify the feasibility of the distributed data readout method. In this paper, the DAQ software is focused on data collection, event building, status monitoring and system controlling. Laboratory tests confirmed the function of the DAQ software and show that the overall data transfer rate of a single data transmission path can reach up to about 550Mbps which already meet the demand.
