Tunka-Rex: Status and Results of the First Measurements (RICAP 2013)

Understand

Tunka-Rex is the radio extension of 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 approximately $10^{16}$ to $10^{18}$ eV.
• Tunka-Rex extends this detector with 25 antennas spread over an area of 1 km$^2$.
• It is triggered externally by Tunka-133, and detects the radio emission of the same air showers.
