The variation of the electromechanical coupling factor of lead zirconate titanate (PZT) was studied using a piezoelectric PZT disk exposed to a 400MeV/n xenon beam. The resonant and antiresonant frequencies were measured in pairs by an impedance analyzer in situ manner. A systematic behavior of the pairs resulted in a decrease of the coupling factor. It was found that the coupling factor linearly decreased with increasing integrated beam energy incident on the PZT disk while its surface temperature was equilibrium at room temperature. We discuss a possible PZT-based radiation detector for practical use in a high-radiation field.

高能重离子辐照对压电锆钛酸铅钛酸盐机电耦合系数的影响

使用暴露于400MeV / n氙气束的压电PZT圆盘研究了锆酸钛酸铅（PZT）机电耦合系数的变化。谐振和反谐振频率通过阻抗分析仪成对测量。偶对的系统行为导致耦合因子的减小。发现在室温下表面温度达到平衡时，耦合因子随着入射在PZT盘上的积分束能量的增加而线性减小。我们讨论了可能在高辐射领域中实际使用的基于PZT的辐射探测器。
