论文摘要
对于进一步的重力波（GW）检测，发明一种技术以减少各种镜像位移噪声在低频下以地面检测器的形式占主导地位是很重要的。中子位移无空中干涉仪（DFI）是降低较低频率下所有镜像位移噪声的工具之一。在本文中，我们描述了中子DFI的进一步简化配置，以中子的入射方向。在新的构型中，中子以四个速度的单向发生率进入干涉仪，而不是以前报道的两个相反方向的双向发生率，而不是两个速度的双向发生率。中子DFI的这种简化对于原则实验证明具有重要意义。
For further gravitational wave (GW) detections, it is significant to invent a technique to reduce all kinds of mirror displacement noise dominant at low frequencies for ground-based detectors. The neutron displacement-noise-free interferometer (DFI) is one of the tools to reduce all the mirror displacement noise at lower frequencies. In this paper, we describe a further simplified configuration of a neutron DFI in terms of neutron incidence direction. In the new configuration, neutrons enter the interferometer with unidirectional incidence at four speeds as opposed to two bidirectional incidences of opposite directions at two speeds as reported previously. This simplification of the neutron DFI is significant for proof-of-principle experiments.
