论文摘要
地球物理噪声的来源，例如风，海浪和地震，可能会影响引力波干涉仪，从而导致灵敏度恶化和数据吸收差距。在1年的O3运行（2019年4月1日至2020年3月27日）中，处女座的合作收集了一个具有统计学意义的数据集，以研究检测器对各种环境条件的响应。我们使用这些数据将环境参数与全球检测器性能相关联，例如观察范围，占空比和控制损失。在可能的情况下，我们确定了检测器中的弱点，并阐述了对下一次O4的外部干扰的鲁棒性的策略，计划于2022年夏季开始。在本文中，我们介绍了这项研究的初步结果。
Sources of geophysical noise, such as wind, sea waves and earthquakes, can have an impact on gravitational wave interferometers causing sensitivity worsening and gaps in data taking. During the 1-year long O3 run (April 1st 2019 to March 27th 2020), the Virgo Collaboration collected a statistically significant dataset to study the response of the detector to a variety of environmental conditions. We used these data to correlate environmental parameters to global detector performance, such as observation range, duty cycle and control losses. Where possible, we identified weaknesses in the detector and we elaborated strategies to improve Virgo robustness against external disturbances for the next run O4, planned to start in summer 2022. In this article we present preliminary results of this study.
