论文摘要
我们在费米国家加速器实验室研究并分析了MAGIS-100原子干涉实验的特定部位系统。随着原子干涉仪从实验室环境中移出，必须实施噪声源的积极缓解。为了告知实验设计的研究和开发，我们测量了安装位点的环境温度，湿度和振动。我们发现，温度波动需要为关键子系统和激光系统温度控制的激光室围墙。我们还测量和分析了安装位点上方和下方的振动光谱。还使用来自多个位置的低噪声地震计的输入对重力梯度噪声的地震振动效应进行建模，并使用随机模拟研究了缓解方案，并通过抑制因子进行表征。
We investigate and analyze site specific systematics for the MAGIS-100 atomic interferometry experiment at Fermi National Accelerator Laboratory. As atom interferometers move out of the laboratory environment passive and active mitigation for noise sources must be implemented. To inform the research and development of the experiment design, we measure ambient temperature, humidity, and vibrations of the installation site. We find that temperature fluctuations will necessitate enclosures for critical subsystems and a temperature controlled laser room for the laser system. We also measure and analyze the vibration spectrum above and below ground for the installation site. The seismic vibration effect of gravity gradient noise is also modeled using input from a low-noise seismometer at multiple locations and a mitigation scheme is studied using a stochastic simulation and characterized by a suppression factor.
