ANTARES中微子望远镜的定位系统

Positioning system of the ANTARES Neutrino Telescope

Anthony M. Brown

摘要:

ANTARES中微子望远镜于2008年5月完工,位于土伦海岸40公里处,深度约2500米。该望远镜由12个探测器或线路组成,共容纳884个光学模块。每条线都锚定在海底,并通过各个光学模块和顶部浮标的浮力进行牵引。由于海水探测介质的流体性质和探测器线的灵活性质,ANTARES望远镜的光学模块可能会受到高达数米的垂直偏差的影响,因此需要实时定位。ANTARES望远镜的实时定位是通过一个声学定位系统和倾斜仪和指南针的网格相结合来实现的。这些独立的和互补的系统被用来计算一个整体适合每个单独的检测线,使我们能够构建一个三维的ANTARES中微子望远镜的图像,精度小于10厘米。本文描述了ANTARES中微子望远镜的定位系统,并讨论了它在12线数据采集的第一年中的性能。

英文摘要:

Completed in May 2008, the ANTARES neutrino telescope is located 40 km off the coast of Toulon, at a depth of about 2500 m. The telescope consists of 12 detect or lines housing a total of 884 optical modules. Each line is anchored to the seabed and pulled taught by the buoyancy of the individual optical modules and a top buoy. Due to the fluid nature of the sea-water detecting medium and the flexible nature of the detector lines, the optical modules of the ANTARES telescope can suffer from deviations of up to several meters from the vertical and as such, real time positioning is needed. Real time positioning of the ANTARES telescope is achieved by a combination of an acoustic positioning system and a lattice of tiltmeters and compasses. These independent and complementary systems are used to compute a global fit to each individual detector line, allowing us to construct a 3 dimensional picture of the ANTARES neutrino telescope with an accuracy of less than 10 cm. In this paper we describe the positioning system of the ANTARES neutrino telescope and discuss its performance during the first year of 12 line data taking.
