Semaine de l'Astrophysique Française (SF2A 2007), Grenoble : France
UHECR observed by the radiodetection experiment CODALEMA
T. Saugrin1
CODALEMA Collaboration(s)

The radiodetection experiment CODALEMA allows to study, on an event-by-event basis, cosmic ray air showers through the detection of the radiated electric field. 2 major upgrades have been made in September 2006: - a new antenna array made up of 16 active dipole antennas, arranged in a cross shape. - 13 new particule detector providing more accurate informations on air showers: primary cosmic ray energy estimation, core shower position... Results from 6 months of measurements: radiodetection efficiency versus energy, arrival direction distribution or showers lateral electric field dependence, will be discussed. Full analysis of a high energy event will be presented.
