摘要

Thermonuclear Experimental Reactor (ITER) is a big international cooperative project. China is in charge of first wall (FW) research which is made of blanker Be, Copper alloy and SS cooling tubes. The inspection of bonding quality between Be-Cu-SS tubes is essentially necessary. According to the structure and material acoustic characteristics, the acoustic amplitude-phase was theoretically analyzed, and a broad-band ultrasonic scanning system and a rotated acoustic mirror device were developed. The experimental results indicate that the broad-band ultrasonic technique is one of the most effective methods to evaluate bounding quality in ITER.
