论文摘要
基于无线电的高能颗粒的检测正在成熟。在本章中，我们着重于检测中微子，其能量超过10 PEV，这些PEV与在极区域中发现的较厚的无线电透明冰相互作用。在冰中相互作用的高能量中微子会产生短持续时间，射频闪烁通过Askaryan效应，可以用安装在浅深度的天线来测量。大量的目标材料和较长的衰减长度约为1公里，可以使庞大的无线电探测器站的巨大仪器具有成本效益的仪器。该探测器结构对超高能量中微子的低通量具有足够的敏感性，以探测超高能量宇宙射线的产生，其起源是天线粒子物理学中最长的谜语之一。我们描述了信号特征，传播效应，检测器设置，合适的检测位点和背景过程。我们概述了当前的实验景观和对未来的展望，在这些景观中，几乎可以通过明智地选择探测器位置来查看整个天空。
Radio-based detection of high-energy particles is growing in maturity. In this chapter, we focus on the detection of neutrinos with energies in excess of 10 PeV that interact in the thick, radio-transparent ice found in the polar regions. High-energy neutrinos interacting in the ice generate short duration, radio-frequency flashes through the Askaryan effect that can be measured with antennas installed at shallow depths. The abundant target material and the long attenuation lengths of around 1 km allow cost-effective instrumentation of huge volumes with a sparse array of radio detector stations. This detector architecture provides sufficient sensitivity to the low flux of ultra-high-energy neutrinos to probe the production of ultra-high-energy cosmic rays whose origin is one of the longest-standing riddles in astroparticle physics. We describe the signal characteristics, propagation effects, detector setup, suitable detection sites, and background processes. We give an overview of the current experimental landscape and an outlook into the future where almost the entire sky can be viewed by a judicious choice of detector locations.
