In this study, experiments have been performed to elucidate the mechanism of the phenomenon visualised by ultrasonograph (ultrasonic echo imaging) when heavy particle beams are irradiated in water. The experiments were carried out at HIMAC, QST-NIRS, using Fe500 MeV/n. In this talk, the experimental results obtained so far will be reported and the discussion towards elucidating the mechanism will be deepened.
