陀螺仪GINGERINO 90天运行分析
Analysis of 90 days operation of the gyroscope GINGERINO
摘要：
GINGERINO是一个方形环形激光器原型，用于研究Gran Sasso地下实验室内的噪音水平。它是为基础物理学准备的，但它为地球物理学和地震学提供了合适的数据。自2017年5月以来，它一直在不断收集数据。对第一个$90$天的分析表明，占空比高于$95\%$，量子散粒噪声极限为$ 10^{-10}(\mathrm{rad}/s)/\sqrt{\mathrm{Hz}}$量级。它位于地震活跃区，记录了意大利中部的部分地震。它在几分之一赫兹的频带内具有很高的灵敏度，因而适用于地震学研究。本分析的主要目的是研究装置的长期响应。简单而快速的例程，以消除来自激光器的干扰已经开发出来。原始数据的Allan偏差在约$10^6s$的积分时间后达到$10^{-7}$，而处理后的数据显示出一个数量级的改善。处理后的数据中存在每日时间尺度的扰动，极移和固体地球潮汐引起的预期信号被这些扰动所覆盖。
英文摘要：
GINGERINO is a square ring-laser prototype, which has been built to investigate the level of noise inside the Gran Sasso underground laboratory. It Is meant for fundamental physics, but it provides suitable data for geophysics and seismology. Since May 2017 it is continuously acquiring data. The analysis of the first $90$ days shows that the duty cycle is higher than $95\%$, and the quantum shot noise limit is of the order of $ 10^{-10}(\mathrm{rad}/s)/\sqrt{\mathrm{Hz}}$. It is located in a seismically active area, and it recorded part of the of central Italy earthquakes. Its high sensitivity in the frequency band of fraction of Hz makes it suitable for seismology studies. The main purpose of the present analysis is to investigate the long term response of the apparatus. Simple and fast routines to eliminate the disturbances coming from the laser have been developed. The Allan deviation of the raw data reaches $10^{-7}$ after about $10^6s$ of integration time, while the processed data shows an improvement of one order of magnitude. Disturbances at the daily time scale are present in the processed data and the expected signal induced by polar motion and solid Earth tide is covered by those disturbances.
