Abstract:
During their passing through the atmosphere, when colliding with an atmospheric compound, cosmic rays induce cascades of secondary particles called air showers. In the last years, radio detection became a stable technique for the detection of air showers. The largest radio detection array in the world, named AERA (Auger Engineering Radio Array), investigating and assessing different configurations of radio stations while taking efficient measurements in the field, is operating at the Pierre Auger Observatory located in Mallargue, Argentina. Electronic devices have a specific sensitivity towards the temperature of the environment, and implicitly to their intrinsic temperature, as well. This sensitivity is reflected in the amplitude of the recorded signal, since it varies as a function of temperature. Therefore, the amplitude should be corrected for this influence. This research analyses the results of implementing a module of temperature correction in the reconstruction algorithm of air showers within the Offline software framework of the Pierre Auger Observatory.
