Description

In the previous decades, remarkable progress has been made in the detection of electromagnetic emission from cosmic ray air showers. The LOPES experiment, a digital radio interferometer located at KIT (Karlsruhe Institute of Technology), obtained considerable results for the detection at MHz frequencies. Aiming to become competitive with the well-established investigation methods, radio detection has the main purpose of retrieving the complete information from a high-energy cosmic ray, e.g. arrival direction, energy and type of the primary particle. Features of the radio lateral distribution function (LDF) are explored in this work for a precise reconstruction of two fundamental air shower parameters: the primary energy and the shower Xmax. The method presented here has been developed on (REAS3-)simulations, and is applied to LOPES measurements. Despite the high human-made noise at the LOPES site, it is possible to reconstruct both the energy and Xmax for individual events. While the energy resolution is promising and comparable to the one of the co-located KASCADE-Grande experiment, the investigation shows that for a Xmax resolution better than 30 g/cm2, a region with a lower human-made noise level would be needed.
