The LOPES experiment — •Nunzia Palmieri — Karlsruher Institut für Technologie (KIT)

LOPES is a digital interferometric antenna array co-located with the particle detector KASCADE-Grande at the Karlsruhe Institute of Technology (KIT).Being one of the pioneers in the detection and in the interferometric analysis of the radio emission from cosmic ray air showers at MHz frequencies, LOPES still provides us with relevant results.
Since the first measurements in 2003, LOPES was reconfigured several times in order to test different setup and antenna types, and to address different questions concerning the radio emission from air showers. In its latest configuration, a tripole antenna is tested, which makes LOPES able to measure all three components of the electric field vector of the radio emission, and to better compare measurements with simulations.
This talk will give an overview of the recent status and outcomes of the LOPES experiment. Thanks to a large statistics of well reconstructed events, LOPES measurements are used for comparison with simulations (REAS and CoREAS), giving a crucial contribution in better understanding the radio emission mechanisms.
The updated results concerning a successful reconstruction of fundamental air shower parameters, such as the arrival direction, the primary energy and the depth of the shower maximum, with reasonably high precision are presented.
