An efficient detector for neutrinos at energies between 10^16 and 10^20 eV will be the ultimate tool to unravel the origin of ultra-high energy cosmic rays (UHECRs). Despite decades of research, the sources of UHECRs remain elusive, mostly due to complex interactions of the charged particles and deflection in magnetic fields. Measuring the neutrino flux related to UHECRs will provide a final say on the sources of UHECRs. Currently operating neutrino detectors are too small for the low flux and cannot be extended to volumes that promise a detection, at least not within a realistic budget. The most promising detection technique is radio detection, which can be used to instrument two orders of magnitude larger volumes than current detectors at moderate costs. Pilot-arrays have proven the suitability of the method, however, the scaling of the current arrays needs additional work with respect to an efficient detector design, analysis methods and sensitivity studies. This proposal will elaborate how the proposer is an excellent position to ensure a successful installation and operation of a large radio detector for neutrinos within the Emmy Noether Program as part of a large international collaboration. Her experience from radio arrays for air showers in hardware, analysis and simulation requirements, will be combined with the knowledge gained from the neutrino pilot-arrays, innovative analysis techniques and Monte Carlo simulations to influence critical design decisions and ensure a leading contribution to the science results. The radio technique has a great potential for future neutrino efforts and is a field of expertise that has currently no strong presence in Germany.

能量在10^16和10^20 eV之间的中微子的有效探测器将是解开超高能宇宙射线（UHECR）起源的最终工具。尽管经过几十年的研究，超高频电子回旋共振的来源仍然难以捉摸，主要是由于带电粒子的复杂相互作用和磁场中的偏转。测量与UHECR相关的中微子通量将为UHECR的来源提供最终的说法。目前运行的中微子探测器对于低通量来说太小了，并且不能扩展到保证探测的体积，至少在现实的预算范围内。最有前途的检测技术是无线电检测，它可以用来仪器两个数量级以上的体积比目前的检测器在中等成本。试点阵列已经证明了该方法的适用性，但是，目前的阵列的缩放需要额外的工作，高效的检测器设计，分析方法和灵敏度研究。 该提案将详细说明提案人如何成为确保在艾美诺特计划内成功安装和操作大型中微子无线电探测器的绝佳位置，作为大型国际合作的一部分。她在硬件，分析和模拟要求的空气淋浴无线电阵列的经验，将与中微子先导阵列，创新分析技术和蒙特卡罗模拟获得的知识相结合，以影响关键的设计决策，并确保对科学成果的领先贡献。无线电技术对未来的中微子研究具有巨大的潜力，目前在德国还没有很强的专业知识。
