摘要
正在研制的低温高密度核物质测量谱仪(CSR External-target Experiment,CEE)系统经过触发后平均数据率可达2 GB/s。针对整个谱仪的设计需求,本文提出了通用的流处理数据获取架构Data-Matrix(DMatrix),并设计了D-Matrix在飞行时间探测器(Time-of-Flight,TOF)子系统应用的具体方案。TOF系统的数据获取(Data Acquisition,DAQ)系统中使用光纤、PCIe总线等高速串行通信方式完成从前端电子学(Front End Electronic,FEE)到服务器阵列的数据传输,并通过具有统一接口的流处理节点的部署和级联来完成事例组装、命令路由、状态实时监测和数据显示与存储等任务。除此之外,TOF系统的数据获取系统在硬件和逻辑设计上具有良好的通用性,可以兼容其他子探测器系统,并应用于CEE实验的全局系统中。
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.
