摘要

本文提出了一种用于PEP-II B工厂探测器的触发和数据采集系统的设计。该系统是异步的、数据驱动的和可扩展的。设计目标包括正交跟踪和量热触发，最小死区时间，优雅的退化，高效率，以及面对高到足以淹没重建的背景时的有用性能。还介绍了基于8位fadc的漂移室和基于新型定制集成电路的量热计的仪器，具有范围编码(CARE)的电荷放大器和10位adc。本设计在VME和VXI板条箱中采用商用嵌入式cpu。>

Design Of A Trigger And Data Acquisition System For A Detector At Pep-II

This paper proposes a design of a trigger and data acquisition system for a detector at the PEP-II B Factory. The system is asynchronous, data-driven, and scalable. Design goals include orthogonal tracking and calorimetric triggers, minimal dead time, graceful degradation, high efficiency, and useful performance in the face of backgrounds so high as to overwhelm reconstruction. Also described are instrumentation of the Drift Chamber, based on 8-bit FADCs, and of the Calorimeter, based on a new custom integrated circuit, the Charge Amplifier with Range Encoding (CARE), and 10-bit ADCs. This design employs commercial embedded CPUs in VME and VXI crates. >
