IceCube数据采集系统：信号采集、数字化和时间戳
The IceCube Data Acquisition System: Signal Capture, Digitization, and Timestamping
摘要：
IceCube是一个正在南极建造的公里级中微子观测站，其传感器位于深冰（InIce）和表面（IceTop）。这些传感器被称为数字光学模块（DOM），可以检测、识别和标记来自光学切伦科夫辐射光子的信号。DOM主板（MB）数据采集子系统通过单根双绞铜线连接到IceCube实验室（ICL）的中央DAQ，并按需传输分组数据。通过定期向DOM传输精确定时的模拟信号，与中央GPS纪律时钟同步，在整个阵列中保持时间校准。这里描述了DOM MB的设计目标和随之而来的特性、功能能力和初始性能，以及DOM组合阵列作为一个系统的操作。第一批InIce串和IceTop站的经验表明，系统设计和性能目标已经实现。
英文摘要：
IceCube is a km-scale neutrino observatory under construction at the South Pole with sensors both in the deep ice (InIce) and on the surface (IceTop). The sensors, called Digital Optical Modules (DOMs), detect, digitize and timestamp the signals from optical Cherenkov-radiation photons. The DOM Main Board (MB) data acquisition subsystem is connected to the central DAQ in the IceCube Laboratory (ICL) by a single twisted copper wire-pair and transmits packetized data on demand. Time calibration is maintained throughout the array by regular transmission to the DOMs of precisely timed analog signals, synchronized to a central GPS-disciplined clock. The design goals and consequent features, functional capabilities, and initial performance of the DOM MB, and the operation of a combined array of DOMs as a system, are described here. Experience with the first InIce strings and the IceTop stations indicates that the system design and performance goals have been achieved.
