| contents | The Renaissance of Radio Detection of Cosmic Rays Tim Huege Física, Astronomía y Matemáticas cosmic rays Radio detection Nearly 50 years ago, the first radio signals from cosmic ray air showers were d etected. After many success- ful studies, however, research ceased not even 10 years later. Only a decade ago, the field was revived with the application of powerful digital signal processing techniques. Since then, the detection technique has matured, and we are now in a phase of transition from small-scale experiments accessing energies below 10 18 eV to experiments with a reach for energies beyond 10 19 eV. We have demonstrated that air shower radio signals carry information on both the energy and the mass of the primary particle, and current experiments are in the process of quantifying the precision with which this information can be accessed. All of this rests on solid understanding of the radio emission processes, which can be interpreted as a coherent superposition of geo-magnetic emission, Askaryan ch arge-excess radiation, and Cherenkov-like coherence effect s arising in the density gradient of the atmosphere. In this article, I highlight the “state of the art” of radio detection of cosmic rays and briefly discuss its perspectives for the next few years. 2014 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46432476010 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.5 Vol.44 |
