用South Pole声学试验装置测量南极冰中声速与深度的关系

Measurement of sound speed versus depth in Antarctic ice with the South Pole Acoustic Test Setup

Freija Descamps

摘要:

在南极冰中声学中微子探测阵列的可行性和设计取决于冰的声学特性。南极声学测试装置(SPATS)的建立是为了评估冰在1至100 kHz频率范围内的声学特性。垂直声速剖面与表面噪声的折射程度有关,并决定了中微子方向的重建精度。介绍了SPATS对压力波和剪切波的声速分析。

英文摘要:

The feasibility and design of an acoustic neutrino detection array in the South Pole ice depend on the acoustic properties of the ice. The South Pole Acoustic Test Setup (SPATS) was built to evaluate the acoustic characteristics of the ice in the 1 to 100kHz frequency range. The vertical sound speed profile relates to the level of refraction of the surface noise and determines the reconstruction precision of the neutrino direction. The SPATS speed of sound analysis for pressure and shear waves is presented.
