NEMO的状态:来自NEMO相位1检测器的结果

Status of NEMO: results from the NEMO Phase-1 detector

Carla Distefano

摘要:

NEMO协作组安装了一个水下探测器,其中包括可能的千米$^3$中微子望远镜的大部分关键要素:一个四层塔(称为迷你塔)和一个接线盒,包括数据传输、配电、定时校准和声学定位系统。这些技术解决方案将在KM3NeT联盟内进行评估,其中包括为建造km $^3$探测器而提出的其他技术解决方案。本测试实验的主要测试是验证上述提出的设计解决方案。我们目前的分析结果与NEMO迷你塔收集的数据。通过声学定位系统确定光电倍增管的位置,利用光电倍增管探测到的信号重建大气μ子的径迹。测量了大气μ介子的角分布,并与蒙特卡罗模拟的结果进行了比较。

英文摘要:

The NEMO Collaboration installed an underwater detector including most of the critical elements of a possible km$^3$ neutrino telescope: a four-floor tower (called Mini-Tower) and a Junction Box, including the data transmission, the power distribution, the timing calibration and the acoustic positioning systems. These technical solutions will be evaluated, among others proposed for the construction of the km$^3$ detector, within the KM3NeT Consortium. The main test of this test experiment was the validation of the proposed design solutions mentioned above. We present results of the analysis of data collected with the NEMO Mini-Tower. The position of PMTs is determined through the acoustic position system; signals detected with PMTs are used to reconstruct the tracks of atmospheric muons. The angular distribution of atmospheric muons was measured and results were compared with Monte Carlo simulations.
