摘要:
利用原子干涉仪(AIs)进行弱等效原理(WEP)检验的精度在微重力环境下有望达到极高水平。中国空间站(CSS)中的微重力科学实验柜(MSLC)能够提供比CSS本身更高水平的微重力,这为需要高微重力的科学实验提供了良好的实验环境。我们设计并实现了一种双物种冷铷原子干涉仪的有效载荷。该有效载荷高度集成,尺寸为460毫米×330毫米×260毫米。它将被安装到MSLC中以开展高精度WEP检验实验。在本文中,我们介绍了有效载荷设计的约束条件和指导原则、科学有效载荷的组成与功能、在空间中的预期测试精度,以及地面测试实验的一些结果。
英文摘要:
The precision of the weak equivalence principle (WEP) test using atom interferometers (AIs) is expected to be extremely high in microgravity environment. The microgravity scientific laboratory cabinet (MSLC) in the China Space Station (CSS) can provide a higher-level microgravity than the CSS itself, which provides a good experimental environment for scientific experiments that require high microgravity. We designed and realized a payload of a dual-species cold rubidium atom interferometer. The payload is highly integrated and has a size of 460 mm * 330 mm * 260 mm. It will be installed in the MSLC to carry out high-precision WEP test experiment. In this article, we introduce the constraints and guidelines of the payload design, the compositions and functions of the scientific payload, the expected test precision in space, and some results of the ground test experiments
