Evaluation of SALLA Antennas for Radio Observations of Inclined Air Showers — •Vladimir Lenok for the Pierre Auger collaboration — Institute for Nuclear Physics, Karlsruhe Institute of Technology, Karlsruhe, Germany
The Auger Engineering Radio Array (AERA) is a cosmic-ray experiment at the Pierre Auger Observatory in the Province of Mendoza, Argentina. The array comprises about 150 antennas of log-periodic and butterfly types spread over an area of 17 km2 and is used for detection of radio emission from air showers of energies above 0.1 EeV in the band of 30–80 MHz. Recently, at the site of AERA three short aperiodic loaded loop antennas (SALLA) were installed. These three antennas are a pathfinder for a future radio detector aimed at the observation of inclined air showers at the Auger Observatory. Combined radio and particle measurements are sensitive to the type of the primaries, even for the inclined showers. This will enable to resolve the recently found anisotropy into heavy and light components and at the same time increase the area of observed sky. In this talk the results of a preliminary analysis will be presented.
