88. Characterisation and testing of the KM3NeT acoustic positioning system

Francesco Simeone (INFN)

In underwater neutrino telescopes, the search of point-like sources through the Cherenkov detection technique requires a precise knowledge of the positions of thousands of optical sensors, spread in a volume of a few cubic kilometres. In KM3NeT the optical sensors are hosted in 700 m high semi-rigid structures, called detection units, which move under the effects of underwater currents. These...

60. Acoustic neutrino detection investigations within ANTARES and prospects for KM3NeT

The acoustic neutrino detection technique is a promising approach for future large-scale detectors with the aim of measuring the small expected flux of cosmogenic neutrinos at energies exceeding 100 PeV. It suggests itself to investigate this technique in the context of underwater Cherenkov neutrino telescopes, in particular KM3NeT, because acoustic sensors are present by design to allow for...

70. Fiber optic hydrophones for acoustic neutrino detection

Acoustic detection may provide way to observe ultra-high energy cosmic neutrinos, i.e. energies above 10$^{18}$ eV, and their extra-galactic sources [1, 2]. The expected flux of cosmic neutrinos with ultra-high energy is low, so that large scale neutrino telescopes are needed for this emerging field of astroparticle physics. Using the acoustic signals induced by a neutrino interaction in...

72. A compact array calibrator to study the feasibility of the acoustic neutrino detection

Miguel Ardid (UPV)

Underwater acoustic detection of ultra-high-energy neutrinos was proposed long time ago since a short bipolar pressure pulse with ‘pancake’ directivity is produced and propagated when this particle interacts with a nucleus in water. The idea is to build a telescope that consists of thousands of acoustic sensors deployed in deep-sea that will monitor hundreds of cubic kilometres of water...

98. The Askaryan Radio Array: Status and new results.

Prof. Albrecht KARLE (Univ. of Wisconsin-Madison)

14/09/2015, 17:40

The observation of cosmic neutrinos can offer insights into the sources of highest energy cosmic rays and energetic process that are involved to generate them. IceCube has reported neutrinos with energies beyond 10$^{15}$ eV. Much larger detection volumes are needed to fully explore the energy region beyond 10 or 100 PeV. The Askaryan Radio Array (ARA) is designed to use the...

79. The ARIANNA Hexagonal Radio Array performance and prospects

Allan Hallgren (Uppsala University)

14/09/2015, 17:55

Detection of neutrinos in the EeV range by observation of radio pulses from the Askaryan effect is proposed by several collaborations. The ARIANNA collaboration is one of them. ARIANNA investigates the possibility to use the unique conditions of the Ross Ice-shelf. The site is isolated with very low levels of anthropogenic radio noise. Reflection of radio signals on the mirror-like ice-sea...

66. Proposal for a Giant Radio Array for Neutrino Detection

Olivier Martineau (CNRS)

High-energy neutrino astronomy will probe the working of the most violent phenomena in the Universe. The GRAND (Giant Radio Array for Neutrino Detection) project consists of an array of 200 000 radio antennas deployed over a total area of 200 000 km2 in a mountainous site. The array aims at detecting high energy neutrinos (E>10^16 eV) via the measurement of air showers induced by the decay in...
