112. Model of the Lateral Distribution of the Radio Emission from Air Showers in the 70 - 350 MHz Frequency Band

Coleman, Alan

The radio emission from air showers is beamed forward during shower development and produces a characteristic footprint on the ground. This emission imprints the content of electromagnetic particles in the cascade and, via measurements with radio antennas, can be used to study cosmic ray and particle physics. Compared to that of particle detectors, the radio footprint is more complex,...

93. Absolute calibration and investigation of ageing of the AERA radio detectors

Prof. Almeida, Rogerio Menezes de (Universidade Federal Fluminense)

The Auger Engineering Radio Array (AERA) is currently the largest facility to measure radio emissions from extensive air showers. Located at the Pierre Auger Observatory in Argentina, it comprises 150 autonomous radio-detector stations, covering an area of 17 km$^2$, and measures radio waves in the frequency range from 30 to 80 MHz. For the correct interpretation of data collected by AERA...

120. Unfolding the Electromagnetic Field from Voltage Time Traces using a Neural Network Approach

Straub, Maximilian

08/06/2022, 17:05

The Auger Engineering Radio Array (AERA), part of the Pierre Auger Observatory, probes cosmic ray induced air showers via radio measurements. Recovering the three-dimensional electromagnetic field around an antenna from the measured voltage time traces is a challenging task, because the measurement process introduces noise and applies a complex frequency and direction-dependent response. We...

87. A neural network to classify GRAND radio time traces

LE COZ, Sandra

08/06/2022, 17:25

GRAND is a UHE cosmic particles detection project, consisting in a giant, self-triggered, antenna array. Wherever we decide to setup the antennas, we will generally face a high rate of anthropic signals, orders of magnitude higher than the rate of extensive air showers. To avoid the saturation of the acquisition, we need to reject a significant part of the data at the antenna level, with a...

97. Simulations of the antenna response for the Auger Radio Detector

Giaccari, Ugo Gregorio (IMAPP, Radboud University Nijmegen, Nijmegen, The Netherlands)

08/06/2022, 17:45

After more than 15 years of successful operation, the Pierre Auger Observatory is currently undergoing a major upgrade called AugerPrime. The aim is to study the mass composition of ultra-high energy cosmic rays. Part of this upgrade consists in installing a Short Aperiodic Loaded Loop Antenna (SALLA) atop each of the 1660 water-Cherenkov detectors.
To obtain an absolute calibration for the...

140. AugerPrime Radio Detector uncertainty

Fodran, Tomáš

08/06/2022, 18:05

A major upgrade of the Pierre Auger Observatory, AugerPrime, whose main purpose is to improve mass sensitivity studies, will soon be completed. The role of the AugerPrime Radio Detector is to extend the mass-sensitive measurements to high zenith angles in the range of 65 to 85 degrees. Discrimination power between two different primaries also depends on the uncertainty. The main cause of this...

92. Propagating Air Shower Radio Signals to In-ice Antennas

Dr Latif, Uzair Abdul (Vrije Universiteit Brussel)

08/06/2022, 18:25

Radio emissions from cosmic ray showers serve as an essential background signal for in-ice radio detectors in the polar regions. Furthermore, cosmic ray showers can also serve as calibration sources for in-ice radio detectors due to their relatively large flux. Thus, we have adapted CoREAS for simulating their radio signals in in-ice antennas. We present a novel way to upgrade CoREAS such that...
