Oliver Seeger for the Pierre Auger collaboration The Pierre Auger Observatory constitutes the currently largest detector for measurements of ultrahigh energy cosmic rays through extended air showers. Radio signals originating from the shower development have been detected with suitable antennas in the 50MHz regime. The Auger Engineering Radio Array (AERA) is being established to exploit the...

oral presentation

An active dipole antenna is in operation since five years at Nançay (France) in the CODALEMA experiment. A new version of this active antenna has been developed, whose shape gave its name of ‘Butterfly’ antenna. Compared to the previous version, this new antenna has been designed to be more efficient at low frequencies, which could permit the detection of atmospheric showers at large...

55. Advanced digital self-triggering of radio emission of cosmic rays

oral presentation

The Auger Engineering Radio Array AERA will measure the radio emission of extensive air showers. One important component of the experiment is the self trigger system, which has to overcome various sources of background signals to detect the specific short radio pulses introduced by ultra high energetic cosmic rays. The goal of the system is to reduce the original raw data rate down to a...
