论文摘要
我们报告了基于物质波干涉测量法MIGA项目的大规模重力天线的实现。该实验包括一系列冷的RB源与150 m长的光腔相关。 Miga正在LSBB地下实验室建造，该地点受益于低背景噪声，是进行精确重力测量的理想前提。 MIGA设施将是基于原子干涉法的新一代GW探测器的演示者，该原子干涉仪可以打开观察GWS的范围窗口。我们在这里描述了仪器构造的状态，重点是LSBB的基础设施工作以及天线真空容器的实现。
We report the realization of a large scale gravity antenna based on matter-wave interferometry, the MIGA project. This experiment consists in an array of cold Rb sources correlated by a 150 m long optical cavity. MIGA is in construction at the LSBB underground laboratory, a site that benefits from a low background noise and is an ideal premise to carry out precision gravity measurements. The MIGA facility will be a demonstrator for a new generation of GW detector based on atom interferometry that could open the infrasound window for the observation of GWs. We describe here the status of the instrument construction, focusing on the infrastructure works at LSBB and the realization of the vacuum vessel of the antenna.
