Seven years of Tunka-Rex operation — •Pavel Bezyazeekov for the Tunka-Rex collaboration — Applied Physics Institute, Irkutsk State University
The Tunka Radio Extension (Tunka-Rex) is an antenna array located in the Tunka Valley in Siberia. It measures the radio emission of cosmic-ray air showers with energies up to EeV. It is triggered by the Tunka-133 air-Cherenkov timing array (during nights) and by the Tunka-Grande array of particle detectors (remaining time). The configuration of Tunka-Rex changed over its runtime from 18 to 57 antennas in an area of 1 km2 and up to 6 satellite antennas extending the total area to 3 km2. During its lifecycle Tunka-Rex has demonstrated that a cost-effective and full duty-cycle radio detector can reconstruct the energy and shower maximum with a precision comparable to optical detectors. Moreover, it was shown that cosmic-ray setups, which use different detection techniques and are placed in different locations, can be cross-calibrated via their radio extensions. These results are showing the prospects of application of the radio technique for future large-scale experiments for cosmic-ray and neutrino detection. For the time being Tunka-Rex is switching from active measurements to the data analysis and publication of corresponding software and data in the open-access data center with online analysis features. In this report we present the current status of the array and give an overview of the results achieved during these years.
