Abstract

The DO detector at Fermilab has been collecting data with its new, Ethernet-based Data Acquisition (DAQ) System since spring 2002. The system was built almost exclusively with commercially available components, and designed to read in event fragments at a rate of 1 kHz from about 70 VME crates, assemble the events with a typical size of 250 kB and pass them to the Level 3 trigger farm, composed of about 160 CPUs, for final event selection. Accepted events are sent to the online system to he stored on tape at an average rate of 50 Hz. The event fragments are read out over VME using Single Board Computers (SBCs) and sent to the trigger farm through 100 Mb/s and 1 Gb/s Ethernet connections via a series of Ethernet switches. This paper gives an overview of the main components of the DAQ and trigger system and reports on its performance during the first year of operation.

基于以太网的费米实验室DO实验数据采集系统

自2002年春季以来，费米实验室的DO探测器一直在使用其新的基于以太网的数据采集(DAQ)系统收集数据。该系统几乎完全由商用组件构建，旨在以1 kHz的速率从大约70个VME板条箱中读取事件片段，将典型大小为250 kB的事件组装起来，并将它们传递给由大约160个cpu组成的3级触发场，以进行最终的事件选择。被接受的事件被发送到在线系统，以平均50赫兹的速率存储在磁带上。事件片段使用单板计算机(sbc)在VME上读出，并通过一系列以太网交换机通过100mb /s和1gb /s以太网连接发送到触发场。本文概述了DAQ和触发系统的主要组成部分，并报告了其第一年运行期间的性能。
