Peculiarities of acoustic oscillation generation in solid targets by pulsed proton beams

Experimental studies using proton linear accelerator were conducted to investigate formation peculiarities of acoustic radiation occurring at interaction of proton pulsed beam with solid-body targets and its space-time structure. Studies were conducted within wide range of energy, pulse duration and current density of charged particle beam. The parameters of the used accelerator of protons were as follows: particle energy -37.8, 72, 100 MeV; density of particle flux within the pulse - 1 x 1010 - 1.5 x 1011 fr./cm2; duration of current pulse -0.3-60 mks. The conducted experimental studies show, that sound generation in solid-state bodies, by beams of heavy charged particles is characterized by a number of peculiar features in contrast to generation in liquid-state targets. Besides, there are stable correlation bonds between parameters of charged particle beam and space-time characteristics of the generated acoustic radiation. 9 refs., 4 figs
