| Research Abstract |
In order to estimate the damage on the inner surface of the structure, relationships between ultrasonic waveform and the amount of damage was clarified by using the contactless and remote controlled measuring technique. The optimal measurement conditions for detecting minute damage were found out. Because the ultrasonic wave propagating in the structure which includes the liquid was influenced the liquid, the influence was taken into account in the ultrasonic measurement. In consideration of the above result, the measuring system based on the laser Doppler vibrometer was developed and the vibration due to proton beams could be measured with sufficient accuracy to monitor the mercury target vessel. This measuring system can be applied as the monitoring system for the apparatus used under the extreme environment.
