本文介绍了ATLAS感兴趣区域生成器（RoIB）的设计、测试和生产。该器件用作ATLAS LHC探测器的1级触发器和高电平触发器（HLT）场之间的接口。它将事件子集的所有1级数据分发给少数（16个或更少）单个商品处理器。这些处理器又将此信息提供给HLT。这允许HLT使用1级信息将数据请求缩小到1级已识别出感兴趣对象的检测器区域。
This article describes the design, testing and production of the ATLAS Region of Interest Builder (RoIB). This device acts as an interface between the Level 1 trigger and the high level trigger (HLT) farm for the ATLAS LHC detector. It distributes all of the Level 1 data for a subset of events to a small number of (16 or less) individual commodity processors. These processors in turn provide this information to the HLT. This allows the HLT to use the Level 1 information to narrow data requests to areas of the detector where Level 1 has identified interesting objects.
