Present status and prospects of the Tunka Radio

Tunka-REX Collaboration; Kostunin, Dmitriy

Abstract (englisch):

The Tunka Radio Extension (Tunka-Rex) is a digital radio array operating in the frequency band of 30-80 MHz
and detecting radio emission from air-showers produced by cosmic rays with energies above 100 PeV. The
experiment is installed at the site of the TAIGA (Tunka Advanced Instrument for cosmic rays and Gamma
Astronomy) observatory and performs joint measurements with the co-located particle and air-Cherenkov
detectors in passive mode receiving a trigger from the latter. Tunka-Rex collects data since 2012, and during
the last five years went through several upgrades. As a result the density of the antenna field was increased by
three times since its commission. In this contribution we present the latest results of Tunka-Rex experiment,
particularly an updated analysis and efficiency study, which have been applied to the measurement of the
mean shower maximum as a function of energy for cosmic rays of energies up to EeV. The future plans are
also discussed: investigations towards an energy spectrum of cosmic rays with Tunka-Rex and their mass
composition using a combination of Tunka-Rex data with muon measurements by the particle detector Tunka-
