The development of the acoustic detector of ultra high-energy cosmic neutrinos on the base of the hydroacoustical planar array with large wavelength dimensions

Objective

The objectives of the project are the following:
- to study possibilities of using the hydroacoustic detectors with registering volumes larger than 1 cubic kilometre for ultrahigh and super high energy (10^15-10^21eV) neutrino astrophysics;
- to develop scientific - technical background for the development of the multichannel measurement system which could search for acoustic signals produced by super high energy (10^19- 10^21eV) neutrinos in water, such system could be constructed on the base of the existing stationary hydroacoustic antenna array of 2400 hydrophones near Kamchatka (hydroacoustic station HAS was performed by "Morfizpribor", St.Petersburg):
- to investigate possibilities of the design of the stationary acoustic neutrino telescope with the "low" threshold of detection energy (10^15-10^15 eV).
To carry out these goals we plan:
- to make an analysis of the hydrologycal-acoustical (background) conditions near the detector sites (Kamchatka, the Ionian Sea):
- to develop the simulation procedures for electron - hadron cascades in water taking into account fluctuations and the Landau-Pomeranchuk-Migdal effect;
- to calculate and simulate acoustic fields of signals generated by neutrino induced cascades, to simulate the acoustic wave Propagation and to analyse the effectivity of their delectability By acoustic antenna;
- To evaluate the optimal algorithms for the detection and The pulse signal processing;
- To calculate an effective volume of the acoustic neutrino Telescope;
- To determinate basic technical and design parameters of the Measurement system;
- To develop and to make an imitator of acoustic signals For calibration and propagation tests;
- To measure the acoustic background in situ.
