Radio detection of cosmic ray air showers with the LOPES experiment

Abstract

In the last few years, radio detection of cosmic ray air showers has experienced a true renaissance. In particular, the LOPES project has successfully implemented modern interferometric methods to measure radio emission from air showers. LOPES has confirmed that the emission is coherent and of geomagnetic origin, as expected by the geosynchrotron mechanism, and has demonstrated that a large scale application of the radio technique has great potential to complement current measurements of ultra-high energy cosmic rays.
