我们开发了一种用于引力波探测激光干涉仪的悬挂镜的三摆隔振系统。由于采用高性能永磁体的被动阻尼方法，该系统具有非常简单，紧凑的结构。对低于40 Hz的振动进行了隔振比测量，结果表明，实测值与计算值吻合较好。通过操作安装在隔振系统上的带有反射镜的迈克尔逊激光干涉仪，证明了系统的稳定性。
We have developed a triple‐pendulum vibration isolation system for suspended mirrors used in a laser interferometer for gravitational wave detection. Owing to the passive damping method using high‐performance permanent magnets, the system has a very simple, compact structure. We measured the isolation ratio for vibration below 40 Hz and confirmed that the observed and calculated values are in good agreement. The stability of the system has been demonstrated by operating a Michelson laser interferometer incorporated with a mirror mounted on the vibration isolation system.
