41. Exploiting the radio signal from air showers: the AERA progress

Benoit REVENU (SUBATECH)

5/14/09, 5:00 PM

We will present the last results and status of the Auger Engineering Radio Array (AERA), located inside the Pierre Auger Observatory. AERA, with more than 150 radio stations spread over 17 km2, is the largest radio detector of extensive air showers above 1017 eV. The electric field emitted by secondary electrons and positrons allows to estimate all characteristics of the primary cosmic ray:...

44. Measurement of the cosmic rays flux with the ANITAexperiment

Daniel García-Fernandez

The ANITA experiment consists on an aerostatic balloon flying over Antarctica and carrying a payload with antennas. It was designed to detect the electric field of neutrino-induced showers. However, ANITA has detected the electric field of cosmic ray-induced showers and the ANITA collaboration has used these data to produce the first cosmic ray flux measurement obtained by employing radio as a...

43. Status and perspectives of the radio detection technique of cosmic ray air showers

Olaf Scholten (KVI/University of Groningen)

5/14/09, 6:00 PM

At LOFAR we measure the radio emission from extensive air showers (EAS) in the frequency band of 30-80 MHz in dual-polarized antennas. Through an accurate antenna calibration we can determine the complete set of four Stokes parameters that uniquely determine the linear and/or circular polarization of the radio signal for an EAS. The observed dependency of the circular polarization on azimuth...

45. The ARCADE project

Laura Valore (Istituto Nazionale di Fisica Nucleare)

5/14/09, 6:30 PM

The Atmospheric Research for Climate and Astroparticle DEtection (ARCADE) project started in 2012 and involves research groups from Italy (Naples, Turin and L'Aquila) and Colorado. The target of ARCADE is the comparison of the techniques mostly used in cosmic-rays and gamma-rays experiments to measure the atmospheric aerosol attenuation profiles of the UV light, for a better understanding of...

285. The cosmic ray spectrum in the energy region between 10^12 - 10^16 eV measured by ARGO-YBJ

Paolo Montini (ROMA2)

5/14/09, 7:00 PM

The ARGO-YBJ experiment is a full-coverage air shower detector operating at the Yangbajing International Cosmic Ray Observatory (Tibet, P.R China, 4300 m a.s.l.). The detector was in stable data taking in its full configuration from Nov. 2007 to Dec 2012. More than 10^11 events have been collected and reconstructed. Due to its characteristics (full-coverage, high segmentation,high altitude...

243. Recent development on the realization of a 1-inch VSiPMT prototype

Felicia Carla Tiziana Barbato (NA)

5/14/09, 7:20 PM

The VSiPMT (Vacuum Silicon PhotoMultiplier Tube) is an innovative design for a revolutionary hybrid photodetector. The idea, born with the purpose to use a SiPM for large detection volumes, consists in replacing the classical dynode chain with a SiPM. In this configuration, we match the large sensitive area of a photocathode with the performances of the SiPM technology, which therefore acts...
