Description

Tunka-Rex is the new radio extension to Tunka-133 located in Siberia close to lake Baikal. The latter is a photomultiplier array registering air-Cherenkov light from air showers induced by cosmic-ray particles with initial energies of $10^16$ – $10^18$ eV. Tunka-Rex extends this detector with 20 antennas spread over an area of 1 km2 . It is triggered externally by Tunka-133, and detects the radio emission of the same air showers. The combination of an air-Cherenkov and a radio detector provides a great facility for hybrid measurements and cross-calibration between the two techniques. The main goal of Tunka-Rex is to determine the precision of the reconstruction of air-shower parameters using the radio detection technique. It started operation in autumn 2012. We present the overall concept of Tunka-Rex , the current status of the array and first analysis results.
