27. Status and Prospects of the Auger Engineering Radio ArrayJohannes Schulz, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Darko Veberič, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, 2015, objavljeni znanstveni prispevek na konferenci Opis: The Auger Engineering Radio Array (AERA) is an extension of the
Pierre Auger Observatory. It is used to detect radio emission
from extensive air showers in the 30 - 80 MHz frequency band.
A focus of interest is the dependence of the radio emission on
shower parameters such as the energy and the atmospheric depth
of the shower maximum. After three phases of deployment, AERA
now consists of 153 autonomous radio stations with different
spacings, covering an area of about 17 km2. The size, station
spacings, and geographic location at the same site or near other
Auger extensions, are all targeted at cosmic ray energies above
10[sup]17 eV. The array allows us to explore different
technical schemes to measure the radio emission as well as to
cross calibrate our measurements with the established baseline
detectors of the Auger Observatory. We present the most recent
technological developments and selected experimental results
obtained with AERA.

28. The Energy Content of Extensive Air Showers in the Radio Frequency Range of 30-80 MHzChristian Glaser, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Darko Veberič, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, 2015, objavljeni znanstveni prispevek na konferenci Opis: At the Auger Engineering Radio Array (AERA) of the Pierre Auger
Observatory, we have developed a new method to measure the
total amount of energy that is transferred from the primary
cosmic ray into radio emission. We find that this radiation
energy is an estimator of the cosmic ray energy. It scales
quadratically with the cosmic ray energy, as expected for
coherent emission. We measure 15.8 MeV of radiation energy for
a 1 EeV air shower arriving perpendicular to the geomagnetic
field at the Auger site, in the frequency band of the detector
from 30 to 80 MHz. These observations are compared to the data
of the surface detector of the Observatory, which provide
well-calibrated energies and arrival directions of the cosmic
rays. We find energy resolutions of the radio reconstruction
of 22% for the complete data set, and 17% for a high-quality
subset containing only events with at least five stations with
signal.

29. Lightning Detection at the Pierre Auger ObservatoryJulian Rautenberg, Andrej Filipčič, Gašper Kukec Mezek, Ahmed Saleh, Samo Stanič, Marta Trini, Darko Veberič, Serguei Vorobiov, Lili Yang, Danilo Zavrtanik, Marko Zavrtanik, 2015, objavljeni znanstveni prispevek na konferenci Opis: The Auger Engineering Radio Array, an extension of the Pierre
Auger Observatory with antennas in the MHz range, requires to
monitor the atmospheric conditions, which have a large influence
on the radio emission of air showers. In particular, amplified
signals up to an order of magnitude have been detected as an
affect of thunderstorms. For a more detailed investigation and
more generally, for detecting thunderstorms, a new lightning
detection system has been installed at the Pierre Auger
Observatory in Argentina. In addition, an electric-field mill
measures the field strength on ground level at the antenna
array. With these measurements, data periods affected
by thunderstorms can be identified. Additionally, a lightning
trigger for the water-Cherenkov detectors was developed to read
out individual stations when a lightning was detected nearby.
With these data, a possible correlation between the formation
of lightning and cosmic rays can be investigated even at low
energies of about 10[sup]15 eV. The structure and functionality
of the lightning detection are described and first data
analyses are shown.
