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.

该项目旨在解决引力波探测器中的参数不稳定性问题，以支持国际大型物理实验。该项目是澳大利亚参与新的先进LIGO（激光干涉引力波天文台）引力波探测器的一部分，该探测器旨在实现对引力波的首次探测。项目负责人在2005年做出的预测，即探测器将经历声学不稳定性，在2014年的探测器调试过程中得到了证实。项目小组计划与探测器设计人员和专员密切合作，解决这一问题，使探测器达到其目标灵敏度。
