HADES-South Pole的声学探测水听器
HADES - Hydrophone for Acoustic Detection at South Pole
摘要：
南极声学测试装置（SPATS）位于目前正在建设中的光学中微子观测站IceCube的上部。SPATS由四个管柱组成，深度在冰面以下80米至500米之间，每个管柱有七个阶段。每个阶段都配备了一个声学传感器和一个发射器。2006/07年夏天，三根弦（弦A-C）被部署在南方。2007/08年，SPATS又增加了第四串（D串），配备了第二代传感器和变送器。第二代传感器类型HADES（南极声学探测水听器）由涂有聚氨酯的环形压电元件组成。将讨论传感器的发展，声传输的声阻抗匹配和第一个现场结果的优化。
英文摘要：
The South Pole Acoustic Test Setup (SPATS) is located in the upper part of the optical neutrino observatory IceCube, currently under construction. SPATS consists of four strings at depths between 80 m and 500 m below the surface of the ice with seven stages per string. Each stage is equipped with an acoustic sensor and a transmitter. Three strings (string A-C) were deployed in the austral summer 2006/07. SPATS was extended by a fourth string (string D) with second generation sensors and transmitters in 2007/08. One second generation sensor type HADES (Hydrophone for Acoustic Detection at South Pole) consists of a ring-shaped piezo-electric element coated with polyurethane. The development of the sensor, optimization of acoustic transmission by acoustic impedance matching and first in-situ results will be discussed.
