ARIANNA水平宇宙线(HCR)站是一个天线阵列,目的是探测由大约0.1 EeV以上的宇宙线产生的近水平广泛空气簇射(EAS)发射的射频脉冲,以及超高能掠地辐射。 联系我们 Au}$从附近的山上出来。2016年12月,在南极洲罗斯冰架部署了一个原型站,该原型站由冰上方的四个对数周期偶极天线组成,频率范围为140-500 MHz。本文介绍了ARIANNA-HCR的仪器和收集的数据集。接下来,校准使用地基和球载发射机和由此产生的定时和角分辨率。最后给出了宇宙线EAS候选者搜索的第一个结果及其角分布。最后介绍了ARIANNA-HCR站的扩建方案。
ARIANNA Horizontal Cosmic Ray (HCR) station is an antenna array aiming at detecting RF impulses emitted from nearly horizontal extensive air showers (EAS) generated by cosmic rays above about 0.1 EeV, and ultra-high energy Earth-skimming $ u_{ au}$ coming out from nearby mountains. A prototype station consisting of four log-periodic dipole antennas above the ice, in frequency range of 140-500 MHz, is deployed at Ross Ice Shelf in Antarctica during December, 2016. In this paper, the instrumentation of ARIANNA-HCR and the data set collected are presented. Next, the calibration using both ground-based and balloon-borne transmitters and the resulting timing and angular resolution are presented. Then the first result on the search of cosmic-ray EAS candidates and their angular distribution are reported. Finally, we present the expansion plan of ARIANNA-HCR station.
