Abstract :
Acoustic detectors were developed using a piezo ceramic compound PZT. The shape of the PZT detector was essential to obtain a high sensitivity. A detector of a spherically shaped shell structure, whose size was 50 mm in diameter and 2 mm thick, was fabricated. Its sensitivity was calibrated to be about 40 mV/Pa at 54 kHz. Using the hydrophone, acoustic signals generated by an electron-induced cascade shower in water was detected. Experimental results were compared with simulation data and confirmed consistency
