摘要:

GINGERino是一个大型框架激光陀螺仪,用于研究意大利中部Gran Sasso地下国际实验室最内部的地面运动。它由一个方形环形激光器组成,侧面为$3.6$ m。在无人值守的情况下,收集了几天的连续测量结果。地震频带内的功率谱密度为$10^{-10} \rm{(rad/s)/\sqrt{Hz}}$级。最大分辨率为$30\,\rm{prad/s}$,积分时间为几百秒。环形激光器定期检测由区域地震和地震引起的地震旋转。宽带地震台站安装在陀螺仪的同一结构上。首先分析了旋转和平移信号之间的相关性。

英文摘要:

GINGERino is a large frame laser gyroscope investigating the ground motion in the most inner part of the underground international laboratory of the Gran Sasso, in central Italy. It consists of a square ring laser with a $3.6$ m side. Several days of continuous measurements have been collected, with the apparatus running unattended. The power spectral density in the seismic bandwidth is at the level of $10^{-10} \rm{(rad/s)/\sqrt{Hz}}$. A maximum resolution of $30\,\rm{prad/s}$ is obtained with an integration time of few hundred seconds. The ring laser routinely detects seismic rotations induced by both regional earthquakes and teleseisms. A broadband seismic station is installed on the same structure of the gyroscope. First analysis of the correlation between the rotational and the translational signal are presented.
