Lightning Detection at the Pierre Auger Observatory
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.
