Tunka 无线电扩展 (Tunka-Rex) 是一个数字无线电阵列，工作频率为 30-80 MHz，可检测能量高于 100 PeV 的宇宙射线产生的空气簇射无线电发射。该实验安装在TAIGA（宇宙射线和伽马天文学先进仪器）天文台现场，并与同位的粒子和空气切伦科夫探测器以被动模式接收后者的触发进行联合测量。 Tunka-Rex 自 2012 年开始收集数据，并在过去五年中经历了多次升级。结果，天线场的密度自投入使用以来增加了三倍。在这篇文章中，我们介绍了 Tunka-Rex 实验的最新结果，特别是更新的分析和效率研究，这些结果已应用于测量平均簇射最大值作为能量高达 EeV 的宇宙射线能量的函数。还讨论了未来的计划：使用 Tunka-Rex 数据与粒子探测器 Tunka-Grande 的 μ 子测量相结合，研究 Tunka-Rex 的宇宙射线能谱及其质量成分。
The Tunka Radio Extension (Tunka-Rex) is a digital radio array operating in the frequency band of 30-80 MHz and detecting radio emission from air-showers produced by cosmic rays with energies above 100 PeV. The experimentis installed at the site of the TAIGA (Tunka Advanced Instrument for cosmic rays and Gamma Astronomy) observatory and performs joint measurements with the co-located particle and air-Cherenkov detectors in passive mode receiving a trigger from the latter. Tunka-Rex collects data since 2012, and during the last five years went throughseveral upgrades. As a result the density of the antenna field was increased by three times since its commission. In this contribution we present the latest results of Tunka-Rex experiment, particularly an updated analysis and efficiency study, which have been applied to the measurement of the mean shower maximum as a function of energy for cosmic rays of energies up to EeV. The future plans are also discussed: investigations towards an energy spectrum of cosmic rays with Tunka-Rex and their mass composition using a combination of Tunka-Rex data with muon measurements by the particle detector Tunka-Grande.
