Polarization measurements of radio emission of cosmic ray air showers with LOPES

Isar, Paula Gina

It has been recently definitively established that the development of Extensive Air Showers (EAS) which are induced in the Earth's atmosphere by impinging cosmic particles from the outermost space is accompanied by the emission of radio waves. This phenomenon is experimentally investigated by the LOPES experiment, co-located at Karlsruhe Institute of Technology (KIT) with the EAS detector array KASCADE-Grande using traditional detection techniques.

The LOPES experiment is an absolutely amplitude calibrated array of radio antennae for observing radio waves from EAS in the frequency range of 40-80~MHz. The KASCADE-Grande array provides the trigger information and experimentally determined parameters of the associated EAS observed in the energy range of $10^{16}-10^{18}$~eV. The studies are focussed to understand and clarify the phenomena of EAS radio emission, in particular in view of an eventual large scale application of a corresponding detection technique, like in LOFAR (Low Frequency Array for which LOPES is a prototype station) and for the Pierre Auger Observatory.

Until summer 2006, all 30 antennas were equipped in the ea ... mehr
