Abstract
The results of the development of a contactless remote technique for studying thermal characteristics of condensed matter under a pulsed action of an intense heavy-ion beam are presented. This technique is based on measuring the velocity of sound from the time of passage of a probing optoacoustic pulse in a target exposed to an ion beam. To record an acoustic response, we have developed a schlieren system based on the shadow technique for visualizing optical phase nonuniformities. The efficiency of this technique was checked in test experiments on the TWAC-ITEP facility.
