The Matter-wave laser Interferometric Gravitation Antenna (MIGA) is an underground instrument using cold-atom interferometry to perform precision measurements of gravity gradients and strains. Following its installation at the low noise underground laboratory LSBB in the South-East of France, it will serve as a prototype for gravitational wave detectors with a horizontal baseline of 150 meters. Three spatially separated cold-atom interferometers will be driven by two common counter-propagating lasers to perform a measurement of the gravity gradient along this baseline. This article presents the cold-atom sources of MIGA, focusing on the design choices, the realization of the systems, the performances and the integration within the MIGA instrument.
物质波激光干涉引力天线(MIGA)是一种地下仪器,利用冷原子干涉测量法来精确测量重力梯度和应变。在安装于法国东南部低噪声地下实验室LSBB之后,它将作为基线水平为150米的引力波探测器的原型。三个空间分离的冷原子干涉仪将由两束反向传播的共用激光驱动,以测量沿此基线的重力梯度。本文介绍了MIGA的冷原子源,重点关注设计选择、系统实现、性能以及在MIGA仪器中的集成情况。
