| Abstract: | The CSR External-target Experiment(CEE) system under development may reach an average data rate of 2 GB/s after being triggered. In response to the design requirements of the entire spectrometer, a generic stream processing data acquisition architecture D-Matrix is put forward in the article, and a specific scheme of D-Matrix in the Time-of-Flight detector(TOF) subsystem is proposed. The DAQ of the TOF system uses high-speed serial communication methods such as optical fiber and PCIe bus to complete data transmission from Front-End Electronics(FEE) to the servers, and deploys and cascades stream processing nodes with a unified interface to complete event building, command routing, Real-time status monitoring and displaying and data storage tasks. In addition, the DAQ of the TOF system has strong versatility in hardware and logic design, it also can be compatible with other sub-detector systems, and can be further applied to the global system of CEE experiments. |
