Acoustic method of particle detection and its applications for geophysics studies by means of a neutrino beam

Development of the acoustic method of particle detection is presented from the very beginning until current experiments and perspectives. In 1976, Askaryan and Dolgoshein suggested acoustic detection of ultra high energy neutrino in ocean by using an acoustic signal generated according to thermoacoustic mechanism. Practical realization of such project is going on now in several experiments. In 1983, De Rujula, Glashow, Wilson, Charpak presented a possibility to use neutrino beam produced by a multi-TeV proton synchrotron for purposes of geological research. Dedicated studies were started in the group of Dolgoshein. Results of Monte Carlo simulations and measurement of such acoustic signals on the test beams of 70GeV proton accelerator are reported. A new possibility to forecast the earthquakes using the measurement of the velocity of longitudinal sound waves in the region of earthquake by means of usage of neutrino beam as an underground source of acoustic waves is discussed.
