标题： Radiodetection of Neutrinos

摘要： 尽管付出了 100 年的努力，我们对超高能宇宙射线的起源仍然知之甚少。 当能量高于$4\times 10^{19}$电子伏特的宇宙射线质子与宇宙微波背景辐射相互作用，或者在中微子源中发生相互作用时，观测由此产生的中微子，将会揭示大量关于这些粒子的起源和组成的信息。 在过去十年中，许多实验一直在寻找由超高能中微子与南极冰或格陵兰冰以及月球相互作用所产生的带电粒子簇射发射的无线电波。 这些实验尚未观测到中微子信号。 目前有两个小组提议在南极冰层中安装无线电天线，覆盖面积达 100 公里$^3$，从而构建一个足够大的探测器，在几年的运行时间内就能观察到清晰的超高能中微子信号。 显示英文摘要

摘要： Despite 100 years of effort, we still know very little about the origin of ultra-high energy cosmic rays. The observation of neutrinos produced when cosmic-ray protons with energies above $4\times 10^{19}$ eV interact with the cosmic microwave background radiation, or in the neutrino sources, would tell us much about the origin and composition of these particles. Over the past decade, many experiments have searched for radio waves emitted from the charged particle showers produced when EHE neutrinos interact with Antarctic or Greenland ice or the moon. These experiments have not yet observed a neutrino signal. Two groups are now proposing to instrument 100 km$^3$ of Antarctic ice with radio antennas, producing a detector large enough to observe a clear EHE neutrino signal in a few years of operation.
