摘要:

为了探测超高能中微子,ARA和RNO-G等实验利用位于南极或格陵兰的深冰天线,瞄准这些粒子在冰中级联时诱发的射电辐射。此类信号的主要背景之一是由宇宙线簇射产生的射电辐射,这些辐射既可能直接产生于冰中,也可能产生于空气并透射进入冰中,两者均能到达深冰天线。因此,利用深冰天线首次探测到宇宙线将验证这一探测原理,并使我们能够校准探测器。FAERIE,即用于冰中实验的空气簇射射电辐射模拟框架,是一个数值工具,它耦合了CoREAS和GEANT4两种蒙特卡罗程序,以模拟深冰中宇宙线簇射产生的射电辐射。利用该程序,我们将研究宇宙线射电信号特征及其对宇宙线否决系统设计可能产生的影响。

英文摘要:

To detect ultra-high-energy neutrinos, experiments such as ARA and RNO-G target the radio emission these particles induce when cascading in the ice, using deep antennas in South Pole or in Greenland. One of the main backgrounds for such signals is the radio emission generated by cosmic-ray showers, either directly in the ice, or in the air and transmitted to the ice, which can both reach the deep antennas. The first detection of cosmic rays with deep antennas would thus validate this detection principle and allow us to calibrate the detectors. FAERIE, the Framework for the simulation of Air shower Emission of Radio for in-Ice Experiments, is a numerical tool that couples both CoREAS and GEANT4 Monte-Carlo codes to simulate the radio emission from cosmic-ray showers deep in the ice. Using this code, we will investigate cosmic-ray radio signatures and the possible implications on the design of a cosmic-ray veto.
