Controlling parametric instabilities in advanced GW detectors

本项目旨在解决引力波探测器的参数不稳定性问题，为国际大型物理实验提供支持。该项目是澳大利亚参与的新型先进LIGO（激光干涉引力波天文台）引力波探测器的一部分，该引力波探测器的设计目的是实现对引力波的首次探测。2005年，项目负责人预测探测器将经历声学不稳定，这一预测在2014年探测器调试期间得到了证实。项目组计划与探测器设计人员和委员密切合作，解决这一问题，使探测器达到目标灵敏度。

This project aims to solve the problem of parametric instability in gravitational wave detectors to support an international large-scale physics experiment. The project is part of Australia’s participation in the new advanced LIGO (Laser Interferometer Gravitational-Wave Observatory) gravitational wave detectors that have been designed to achieve the first detection of gravitational waves. A 2005 prediction made by the project leaders that the detectors would experience acoustic instabilities was confirmed during detector commissioning in 2014. The project team plans to work closely with the detector designers and commissioners to solve this problem and allow the detectors to achieve their target sensitivity.
