Abstract

Acoustic emission (AE) signal from an HTS tape has a low signal to noise ratio, due to th e large amount of noise caused by the boiling of the liquid cryogen or mechanical vibration from the cryo -cooler. In an attempt to improve the sensitivity of the AE sensor, Pb(Zr 0.54 Ti 0.46 )O 3 + 0.2 wt% Cr 2 O 3 + 1.0 wt.% ND 2 O 5 ceramics sintered at 1200°C was sy nthesized. In addition, the resonance (f r ) and anti-res onance frequencies (f a ) were measured using the spe cimens with various thicknesses (1.0, 1.5, 2.0, 2.5 an d 3.0 mm). According to the test results, large AE s ignals with high frequencies were obtained from the AE sensor fabricated using a piezoelectric disc with a thinner thickness.
