Abstract

An overview of the DO Central Track Trigger (CTT) for the Tevatron Run 2 program is presented. This newly commissioned system uses information from the DO Central Fiber Tracker and Preshower Detectors to generate trigger information for the first level of the three-tiered DO Trigger. The system delivers tracking detector trigger decisions every 132 ns, based on input data flowing at a rate of 475 Gbit per second. Initial results indicate excellent performance of the CTT. First studies of efficiency and trigger performance of the CTT are presented.

第一个结果来自于DO实验的中央跟踪触发器

介绍了Tevatron Run 2程序的DO中央轨道触发器(CTT)的概述。该新系统使用来自DO中央光纤跟踪器和预淋浴探测器的信息，为三层DO触发器的第一级生成触发信息。该系统基于每秒475 Gbit / s的输入数据流，每132 ns提供跟踪检测器触发决策。初步结果表明，CTT具有良好的性能。本文首先对CTT的效率和触发性能进行了研究。
