Experimental facility for checking the possibility to obtain super-high temperature due to acoustic cavitation

An experimental facility developed for checking the possibility to obtain super-high temperature sufficient for thermonuclear reaction D(d, n)3He in an acoustic cavitation is described. The acoustic part of the instrumentation consists of a resonator and a system exciting high amplitude of the acoustic field within the resonator. The cavitation process is controlled with the use of fast neutron pulses. The instrument includes a system of pumping out solute gases from the liquid (acetone enriched with deuterium up to 99%) without losses of matter. Measuring of the field is based on the calibration procedure including observation of sonoluminescence. The system of detection and identification of D(d, n)3He reaction is based on a scintillation detector of fast neutrons and a system of measuring multiparameter events by the correlation technique with separation of neutrons from the γ-radiation background (pulse shape discrimination)
