| Abstract: | 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. |
