激光干涉仪引力波天文台 (LIGO) 等先进引力波探测器需要与地面达到前所未有的隔离水平。运行时,它们测量小于 10−19 m 的运动。地震等强烈的远震事件会破坏探测器的正常功能,并导致数据丢失。为了了解地震对 LIGO 的影响,我们开发了地震预警系统和预测模型。本文描述了一种使用该预警系统的控制策略,可将 LIGO 停机时间减少约 30%。它还提出了在 LIGO 自动化系统中实施这种新地震配置的计划。
Advanced gravitational-wave detectors such as the laser interferometer gravitational-wave observatories (LIGO) require an unprecedented level of isolation from the ground. When in operation, they measure motion of less than 10− 19 m. Strong teleseismic events like earthquakes disrupt the proper functioning of the detectors, and result in a loss of data. An earthquake early-warning system, as well as a prediction model, have been developed to understand the impact of earthquakes on LIGO. This paper describes a control strategy to use this early-warning system to reduce the LIGO downtime by∼ 30%. It also presents a plan to implement this new earthquake configuration in the LIGO automation system.
