摘要:

通卡-雷克斯是通卡宇宙射线天文台的无线电延伸,位于西伯利亚贝加尔湖附近。自2012年10月以来,通卡-雷克斯测量了与非成像空气切伦科夫阵列通卡-133一致的空气阵雨的无线电信号。此外,今年将有更多的天线投入使用,这是由新的闪烁体阵列Tunka-Grande触发的,该阵列测量空气簇射的次级电子和μ子。Tunka-Rex是一个演示器,展示了天线阵列在不损失显著性能的情况下如何经济:我们决定使用简单而强大的SALLA天线,并且我们分别与PMT检测器和解调器共享以从属模式运行的现有DAQ。这意味着Tunka-Rex是外部触发的,不需要自己的基础设施和DAQ进行混合测量。由此,可以研究补充无线电测量的性能和附加值,特别是在大约$10^{17}-10^{18}\,$ eV的能量范围内的重建能量和簇射最大值的精度。在这里,我们展示了第一个结果的能量重建表明,无线电测量可以与空气切伦科夫测量的精度。此外,我们还讨论了Tunka-Rex的未来计划。

英文摘要:

Tunka-Rex is the radio extension of the Tunka cosmic-ray observatory in Siberia close to Lake Baikal. Since October 2012 Tunka-Rex measures the radio signal of air-showers in coincidence with the non-imaging air-Cherenkov array Tunka-133. Furthermore, this year additional antennas will go into operation triggered by the new scintillator array Tunka-Grande measuring the secondary electrons and muons of air showers. Tunka-Rex is a demonstrator for how economic an antenna array can be without losing significant performance: we have decided for simple and robust SALLA antennas, and we share the existing DAQ running in slave mode with the PMT detectors and the scintillators, respectively. This means that Tunka-Rex is triggered externally, and does not need its own infrastructure and DAQ for hybrid measurements. By this, the performance and the added value of the supplementary radio measurements can be studied, in particular, the precision for the reconstructed energy and the shower maximum in the energy range of approximately $10^{17}-10^{18}\,$eV. Here we show first results on the energy reconstruction indicating that radio measurements can compete with air-Cherenkov measurements in precision. Moreover, we discuss future plans for Tunka-Rex.
