南极声学测试装置（SPATS）旨在评估南极冰在10-100 kHz频率范围内的声学特性，以评估南极声学中微子探测阵列的可行性。 SPATS 硬件由部署在南极冰盖上部 500 m 的四根垂直绳组成。这些弦形成一个梯形阵列，最大基线为 543 m。每根弦有七个阶段，配备一个发射器和一个传感器模块（冰川电话）。声音由模块内部的压电陶瓷元件检测或产生。模拟信号通过电缆发送到地面，并由基于 PC 的数据采集系统进行数字化。所有字符串的数据都收集在 IceCube 实验室的中央计算机上，然后通过卫星链路发送到中央数据存储设施或本地存储在磁带上。介绍了 SPATS 及其性能的技术概述。 (C) 2012 Elsevier B.V. 保留所有权利。
The South Pole Acoustic Test Setup (SPATS) was built to evaluate the acoustic characteristics of the South Pole ice in the 10-100 kHz frequency range, for the purpose of assessing the feasibility of an acoustic neutrino detection array at the South Pole. The SPATS hardware consists of four vertical strings deployed in the upper 500 m of the South Pole ice cap. The strings form a trapezoidal array with a maximum baseline of 543 m. Each string has seven stages equipped with one transmitter and one sensor module (glaciophone). Sound is detected or generated by piezoelectric ceramic elements inside the modules. Analogue signals are sent to the surface on electric cables where they are digitized by a PC-based data acquisition system. The data from all strings are collected on a central computer in the IceCube Laboratory from where they are sent to a central data storage facility via a satellite link or stored locally on tape. A technical overview of SPATS and its performance is presented. (C) 2012 Elsevier B.V. All rights reserved.
