Joint measurements of Tunka-Rex, Tunka-133 and Tunka-Grande — •Dmitriy Kostunin for the Tunka-Rex collaboration — KIT, Karlsruhe, Germany

The Tunka Radio Extension (Tunka-Rex) is an array of radio antennas deployed in the Tunka Valley near Lake Baikal, Siberia. It measures the radio emission from extensive air showers created by cosmic-ray primary particles of energies greater than 0.1 EeV. In 2012-2014 Tunka-Rex has been triggered by the air-Cherenkov array Tunka-133. A cross-check between the radio and air-Cherenkov detectors has shown, that Tunka-Rex has precisions of about 15% and 40 g/cm² for the reconstruction of the primary energy and shower maximum, respectively. The scintillator array Tunka-Grande has been deployed recently at the same site. This makes the Tunka facility a unique instrument, which performs combined air-Cherenkov, radio and particle measurements. We present the first results of joint operation of these three detectors and discuss the possibilities of studying the cosmic-ray composition by combining different techniques of detection.
