Abstract :
A pressure wave excited by irradiating liquid chloroform (CHCl3) with a 400 MeV/n xenon (Xe) beam was observed using a detector composed of piezoelectric lead–zirconate–titanate (PZT) elements. The acoustic signals were examined for various beam pulse durations. The amplitude obtained in the first cycle was inversely proportional to the beam pulse duration. It was also found that the time at which the peak in the first cycle appeared was dependent on the location at which each element was set. This suggests that the position at which the Xe beam stops in CHCl3 may be precisely determined with the PZT detector.
