论文摘要
物质波激光干涉吸引力天线(MIGA)是一种使用冷原子干涉法来进行重力梯度和应变精确测量的地下仪器。在法国东南部的低噪声地下实验室LSBB安装后,它将用作水平基线150米的重力波检测器的原型。三个空间分离的冷原子干涉仪将由两个常见的反向传播激光器驱动,以测量沿该基线的重力梯度。本文介绍了MIGA的冷原子来源,重点介绍了设计选择,系统的实现,性能和MIGA仪器中的集成。
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.
