Development of a low-frequency gravitational wave detector using a repetitive microgravity interferometer

我们为第三代引力波探测器研制了重复微重力干涉仪样机。重复微重力干涉仪是一种带有重复自由落体反射镜的低频引力波探测器，其距离是用激光干涉仪测量的。我们开发了一套实现自由落体所必需的夹具释放系统。我们发明了一种新的使用匹配滤波器的数据分析方法，并验证了其有效性。我们还搭建了一个原型探测器，其中两个金属球体通过直线电机重复自由落体，并使用阴影传感器测量球体的距离。我们对其进行操作，获取数据，并对数据进行分析。

We developed a prototype of a repetitive microgravity interferometer for the third-generation gravitational wave detectors. A repetitive microgravity interferometer is a low-frequency gravitational wave detector with repetitively free-falling mirrors whose distance is measured using a laser interferometer. We developed a clamp-release system that is necessary for realization of free fall. We invented a new data analysis method using a matched filter and verified its effectiveness. We also built a prototype detector where two metal spheres repetitively free-fall with a linear motor and the distance of the spheres is measured with a shadow sensor. We operated it, took data, and analyzed the data.
