ANTARES中微子望远镜

The ANTARES Neutrino Telescope

G. Giacomelli

摘要:

ANTARES水下中微子望远镜位于土伦附近地中海2475米深处,正在其12条探测线的最后配置中获取数据。每条线路都配备了75个光电倍增管(PMT),这些光电倍增管安装在海底100米至450米深处的玻璃压力球中,以25个三联体排列。光电倍增管向下看45 °,以便对高能中微子穿越地球相互作用中产生的上行μ子的切伦科夫光具有更好的灵敏度。这种中微子可能来自各种天体物理学来源,尽管大多数是大气中微子。2007年运行的5条谱线的数据产生了足够数量的下行μ子,用于研究探测器性能、垂直μ子强度和重建第一个上行中微子诱导μ子。

英文摘要:

The ANTARES underwater neutrino telescope, at a depth of 2475 m in the Mediterranean Sea, near Toulon, is taking data in its final configuration of 12 detection lines. Each line is equipped with 75 photomultipliers (PMT) housed in glass pressure spheres arranged in 25 triplets at depths between 100 and 450 m above the sea floor. The PMTs look down at 45^o to have better sensitivity to the Cherenkov light from upgoing muons produced in the interactions of high energy neutrinos traversing the Earth. Such neutrinos may arrive from a variety of astrophysical sources, though the majority are atmospheric neutrinos. The data from 5 lines in operation in 2007 yielded a sufficient number of downgoing muons with which to study the detector performances, the vertical muon intensity and reconstruct the first upgoing neutrino induced muons.
