论文摘要
格兰德（Grand）是一系列新提议的无线电阵列，该阵列的联合面积为200,000公里，将在山区部署。它的主要目的是通过这些中微子在岩石中的相互作用和大气中的tau-lepton衰变来测量宇宙超高能tau-neutrinos（E> 1 EEV）。这种衰减产生了空气淋浴，可以从其创建的无线电信号中推断出其特性。巨大的区域使其成为迄今为止提出的最敏感的工具，确保在所有合理的宇宙射线生产和传播模型中测量中微子。同时，Grand将是一个非常通用的天文台，并大量暴露于超高能量的宇宙射线和光子。这次演讲涵盖了科学动机，以及R \＆D阶段所需的阶段方法，以实现最终设计，这将使这款巨大的检测器负担得起的构建，部署和运作。
GRAND is a newly proposed series of radio arrays with a combined area of 200,000 square km, to be deployed in mountainous areas. Its primary goal is to measure cosmic ultra-high-energy tau-neutrinos (E>1 EeV), through the interaction of these neutrinos in rock and the decay of the tau-lepton in the atmosphere. This decay creates an air shower, whose properties can be inferred from the radio signal it creates. The huge area of GRAND makes it the most sensitive instrument proposed to date, ensured to measure neutrinos in all reasonable models of cosmic ray production and propagation. At the same time, GRAND will be a very versatile observatory with enormous exposure to ultra-high-energy cosmic rays and photons. This talk covers the scientific motivation, as well as the staged approach required in the R\&D stages to get to a final design that will make the construction, deployment and operation of this vast detector affordable.
