Abstract
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 $\nu_{\tau}$ 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.
