49. Acoustic parametric techniques for neutrino telescope

Mr Diego Didac Tortosa (UPV)

15/06/2018, 09:20

In this work, we present a compact transmitter array with three elements based on the parametric acoustic sources effect able to reproduce the acoustic signature of an Ultra-High Energy neutrino interaction in water. We also propose to use directive transducers using the parametric technique for the characterization of piezo-ceramic sensors contained in the KM3NeT DOMs. This technique can...

52. Simulation studies for large scale acoustic neutrino detectors

R. Lahmann (Erlangen Centre for Astroparticle Physics)

The AMADEUS system was a submarine acoustic array operating from 2008 until 2015 as a part of the ANTARES neutrino telescope in the Mediterranean Sea. Its design goal was to investigate the feasibility of acoustic neutrino detection in the deep sea. The data taken during its eight years of operation provide a wealth of information for setting up realistic simulations of future acoustic...

58. Fiber optic hydrophones in an acoustic neutrino telescope

Ernst-Jan Buis (TNO)

15/06/2018, 10:00

The technology of ?ber optic hydrophones provides an attractive means to establish an
acoustic neutrino telescope. To implement the technology in a large sensor network,
however, additional requirements have to be met. As the expected number of sensors in
the network will be large, i.e. in the order of 1000-10000, signal multiplexing algorithms
is one of the design drivers that should be...

27. Analog and Digital Signal Processing for Pressure Source Imaging induced by a 20 MeV Proton Beam

Elia Arturo Vallicelli (University of Milano Bicocca)

15/06/2018, 10:20

Introduction. Hadron therapy is an extremely interesting option for cancer treatment, comparing with photon-based radio-therapy. The ion beam deposits very low energy at the interface, practically no dose after the tumor and releases a specific energy peak inside the tissues. This peak is called Bragg Peak and its shaping is also very sharp, increasing this way the dose deposited in depth....

11. A surface radio array for the enhancement of IceTop and its science prospects

Aswathi Balagopal V. (Karlsruhe Institute of Technology)

Radio detection of air showers in the current era has progressed immensely to effectively extract the information of air showers and their properties. It is mainly applied to the detection of cosmic rays and neutrinos. Primary cosmic rays with energies of hundreds of PeV have been successfully measured with the method of radio detection. Current radio experiments measuring such air showers...

45. Towards real-time cosmic-ray identification with the LOw Frequency ARay

Jörg Hörandel (Ru Nijmegen/Nikhef)

15/06/2018, 11:30

poster:

When a cosmic ray interacts with the Earth's atmosphere, it produces a cascade of secondary particles, known as Extensive Air Showers (EAS). Associated with the cascade, a radio signal is emitted through Geomagnetic and Askaryan mechanisms, which can be used for reconstructing the properties of the primary particle.
The LOw Frequency ARay (LOFAR) observatory is a multipurpose radio...

40. Expansion of the LOFAR Radboud Air Shower Array and Updated Calibration of the LOFAR Antennas

Dr Katharine Mulrey (Vrije Universiteit Brussel)

15/06/2018, 11:50

The LOFAR radio telescope measures radio emission from air showers in
great detail. Now, we seek to extend our data taking capabilities.
In this contribution we discuss the expansion of the LOFAR Radboud Air
Shower Array (LORA). LORA is a particle detector array located at the
dense LOFAR core and is used to trigger the read-out of the LOFAR
antennas. By doubling the size of the array, we...

39. A New Concept for High-Elevation Radio Detection of Tau Neutrinos

Prof. Stephanie Wissel (Cal Poly)

15/06/2018, 12:10

Cosmic neutrinos are expected to include a significant flux of tau neutrinos due to flavor mixing over astronomical length scales. However, the tau-neutrino content of astrophysical neutrinos is poorly constrained and a significant flux of cosmogenic tau neutrinos awaits discovery. Earth-skimming tau neutrinos undergo charged-current interactions that result in a tau lepton exiting the Earth....

35. Radio Phased Arrays for the Detection of Ultra-High Energy Neutrinos

eric oberla (uchicago)

15/06/2018, 12:30

Ground-based radio arrays offer a promising future for the measurement of ultra-high energy neutrinos, including the prospect of reducing the radio-detection energy threshold to a level necessary to overlap with the high-energy range probed by IceCube (~10 PeV). Here we describe a phased array of antennas and beamforming electronics, which serves as a highly sensitive and directional trigger...

16. Keeping an ear to the ground for EeV neutrinos

Wladyslaw Henryk Trzaska (University of Jyvaskyla (FI))

15/06/2018, 14:20

Water and ice are the favourite targets for the deployment of acoustic sensors in the search for the characteristic bipolar pressure pulses (BIP) induced by cascades following interaction of very high energy neutrinos with matter. Apparently, there were no previous attempts to try it in bedrock. The reasons are obvious. The costs of deploying a line with sensors into deep sea are considerably...

51. Properties of the Lunar Detection Mode for ZeV Scale Particles with LOFAR

Tobias Winchen (Vrije Universiteit Brussel)

15/06/2018, 14:40

The steep decrease of the flux of ultra-high energy cosmic rays (UHECR)
provides a challenge to answer the long standing question about their origin
and nature. A significant increase in detector volume may be achieved by
employing Earth's moon as detector that is read out using exisiting Earth-bound
radio telescopes by searching for the radio pulses emitted by the particle
shower in the...

48. Preparations for radio air-shower studies with the Murchison Widefield Array

Justin Bray (University of Manchester)

15/06/2018, 15:00

The Murchison Widefield Array (MWA) is a low-frequency (70-300 MHz) aperture-array radio telescope that has the potential to study geomagnetic radio emission from cosmic-ray air showers commensally with its regular astronomical observations. This mode of operation has proven highly effective with the LOFAR telescope, and its implementation with the MWA is a vital step towards its future use...
