Radio Detection of Cosmic Rays

Frank Schroeder (IKP, Karlsruher)

Radio detection has become an additional method for astroparticle physics at energies around 100 PeV and higher. Particle cascades in any medium emit radio pulses, and there is a variety of experiments successfully measuring the radio emission of air showers initiated by cosmic rays. Recently it could be experimentally shown that antenna arrays can compete in precision with the traditional optical methods, i.e., air-Cherenkov and fluorescence light detection, where radio detection brings the intrinsic advantage of being available around the clock. This makes antennas the ideal complement to particle detectors in order to increase the accuracy for the energy and mass composition of cosmic rays. This talk summarizes the status and results of current experiments, and discusses future scientific applications of the radio technique for cosmic rays and neutrinos.
