Invited Talk

After 10 years of efforts, important progress have been made in the field of radio-detection of extensive air showers in the MHz range. The geomagnetic contribution has been proven to be dominant. A secondary process in the shower (probably related to the excess of charges in the shower) has also been detected. The correlation between the detected electric field and the nature and energy of...

30. Recent developments at the Auger Engineering Radio Array

Maximilien Melissas (KIT, IEKP)

19/06/2012, 17:40

Overview Talk

The first phase of the Auger Engineering Radio Array (AERA) has been deployed in the fall of 2010. Currently, the array consists currently of 24 stations distributed over an area of 0.5 km${}^2$. AERA has two different objectives. The first one is to measure cosmic-ray events and to provide the necessary data to improve our understanding of radio emission from air showers. The second objective...

38. Energy Estimation for Cosmic Rays Measured with the Auger Engineering Radio Array

Mr Christian Glaser (RWTH Aachen)

19/06/2012, 18:05

Specialised Talk

The Auger Engineering Radio Array (AERA) is located within the Pierre-Auger Observatory and currently consists of 24 self-triggered radio stations. Observation of radio signals from cosmic rays is confirmed by the surface detector (SD) stations of the observatory which provide well calibrated information on the cosmic ray energies and arrival directions. The response of the radio stations has...

10. Spectral index analysis of the data from the Auger Engineering Radio Array

Specialised Talk

The first stage of the Auger Engineering Radio Array has been deployed at the Pierre Auger Observatory in Argentina and is taking data. It measures radio signals in the MHz range from air showers induced by cosmic rays with energies above 10^17 eV. It is overlooked by the fluorescence telescopes and is located in a dense part of the particle detector array. This allows for cross-calibration of...

4. Cosmic Ray Measurements with LOPES: Status and Recent Results

Frank Schröder (Karlsruhe Institute of Technology (KIT))

20/06/2012, 17:00

Overview Talk

LOPES is a digital antenna array at the Karlsruhe Institute of Technology, Germany, for cosmic-ray air-shower measurements. Triggered by the co-located KASCADE-Grande air-shower array, LOPES detects the radio emission of air showers via digital radio interferometry. We will summarize the status of LOPES and recent results concerning the understanding of the radio emission and the...

14. Comparison of LOPES measurements with CoREAS and REAS 3.1 simulations

Dr Marianne Ludwig (Karlsruhe Institute of Technology)

20/06/2012, 17:25

Specialised Talk

In the previous years, LOPES emerged as a very successful experiment measuring the radio emission from air showers in the MHz frequency range. In parallel, the theoretical description of radio emission was developed further and REAS 3.1 became a well-respected simulation Monte Carlo code. REAS 3.1 as well as CoREAS are based on the endpoint formalism, i.e. no assumptions on the emission...

26. Reconstructing energy and Xmax of cosmic ray air showers using the radio lateral distribution measured with LOPES

Mrs Nunzia Palmieri (Institut fuer Kernphysik (IKP), Karlsruhe Institute of Technology (KIT))

20/06/2012, 17:45

Specialised Talk

In the previous decades, remarkable progress has been made in the detection of electromagnetic emission from cosmic ray air showers. The LOPES experiment, a digital radio interferometer located at KIT (Karlsruhe Institute of Technology), obtained considerable results for the detection at MHz frequencies. Aiming to become competitive with the well-established investigation methods, radio...

53. Some possible interpretations from data of the CODALEMA experiment

Pascal Lautridou (SUBATECH)

20/06/2012, 18:05

Overview Talk

The purpose of the CODALEMA experiment, installed at the Nançay Radio Observatory (France), is to study the radio-detection of cosmic rays of ultra high energy. Distributed over an area of 0.25 km2, the original device has a centralized acquisition, and uses in coincidence an array of particle detectors and an array of active dipoles. A new analysis of energy observables is presented from this...

0. Detecting Radio Emission from Cosmic Rays with LOFAR

Anna Nelles (Radboud University Nijmegen)

22/06/2012, 09:40

Overview Talk

LOFAR (the Low Frequency Array) is the largest radio telescope in the world for observing low frequency radio emission from 10 to 240 MHz. In addition to its use as an interferometric array, LOFAR is now routinely used to detect cosmic ray induced air showers by their radio emission. The LOFAR core in the Netherlands has a higher density of antennas than any other dedicated cosmic ray...

5. Tunka-Rex: a Radio Antenna Array for the Tunka Experiment

Frank Schröder (Karlsruhe Institute of Technology (KIT))

22/06/2012, 10:05

Specialised Talk

Tunka-Rex (Tunka radio extension) will be an array of about 20 antennas at the Tunka experiment close to Lake Baikal in Siberia. The antennas will be connected directly to the data acquisition of the Tunka main detector, a 1 km² large array of 133 non-imaging photomultipliers observing the Cherenkov light of air showers in dark and clear nights. This allows to cross-calibrate the radio signal...

Specialised Talk

With its 1km3 in-ice sensor array complemented by a 1km2 surface array of ice-Cherenkov tanks for particle detection, the IceCube observatory is not only the largest neutrino telescope but also one of the world's most competitive instrument for studying cosmic rays in the PeV to EeV regime. In particular, studying high-energy muons from the shower core in coincidence with particle flux on the...
