摘要:

南极声学测试装置(SPATS)的建立是为了评估南极冰在10 kHz至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硬件包括四个垂直的字符串部署在南极冰盖的上部500米。这些字符串形成梯形阵列,最大基线为543米。每个串有7个阶段,配备一个变送器和一个传感器模块。声音由模块内部的压电陶瓷元件检测或产生。探测信号通过电缆发送到地面,在那里由基于PC的数据采集系统进行数字化。所有字符串的数据都被收集在冰立方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,或者存储在本地磁带上。介绍了SPATS及其性能的技术概述。

英文摘要:

The South Pole Acoustic Test Setup (SPATS) was built to evaluate the acoustic characteristics of the South Pole ice in the 10 kHz to 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 7 stages equipped with one transmitter and one sensor module. 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 send 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.
