HERA-B实验的外跟踪器探测器。部分II:前端电子设备

The Outer Tracker Detector of the HERA-B Experiment. Part II: Front-End Electronics

H. Albrecht et al.

摘要:

HERA-B外部跟踪器是一个大型探测器,具有112674个漂移室通道。它暴露在高达2x10^5/cm^2/s的粒子流中,因此可以应对类似于LHC实验预期的条件。前端读出系统基于ASD-8芯片和定制的TDC芯片,设计满足低噪声、高灵敏度、速率容差和高集成度的要求。TDC系统基于ASIC,该ASIC在总共256个仓内以约0.5ns的仓对时间进行数字化。该芯片还包括一个流水线,用于存储来自128个事件的数据,这是无死区触发和数据采集系统所需的。我们报告的发展,安装和调试的前端电子,包括接地和噪声抑制方案,并讨论其性能的HERA-B实验。

英文摘要:

The HERA-B Outer Tracker is a large detector with 112674 drift chamber channels. It is exposed to a particle flux of up to 2x10^5/cm^2/s thus coping with conditions similar to those expected for the LHC experiments. The front-end readout system, based on the ASD-8 chip and a customized TDC chip, is designed to fulfil the requirements on low noise, high sensitivity, rate tolerance, and high integration density. The TDC system is based on an ASIC which digitizes the time in bins of about 0.5 ns within a total of 256 bins. The chip also comprises a pipeline to store data from 128 events which is required for a deadtime-free trigger and data acquisition system. We report on the development, installation, and commissioning of the front-end electronics, including the grounding and noise suppression schemes, and discuss its performance in the HERA-B experiment.
