Tunka-Rex: Event Reconstruction and Effect of Antenna Alignment — •Yulia Kazarina — Institut für Kernphysik, Karlsruher Institut für Technologie (KIT) — Irkutsk State University (ISU)
The Tunka-Rex experiment (Tunka Radio Extension) has been deployed in autumn 2012 at the territory of the Tunka-133 experiment (Tunka Valley, Republic of Buryatia, Russia), covering an area of approximately 1 km2. Tunka-133 detects the Cherenkov radiation from air showers of cosmic rays at energies E 1016.5 − 1018 eV, and 25 antennas of Tunka-Rex measure the radio emission of the same air showers. Unlike most radio experiments the Tunka-Rex antennas are not aligned along the north-south and east-west axis, but rotated by 45∘ with respect to the geomagnetic north-south axis. Using CoREAS simulations, we studied the effect of the antenna alignment on the efficiency of Tunka-Rex in the presence of noise. This report presents the results of this study as well as methods for the reconstruction of measured air shower events.
