精密测量院研制出精度优于1E的原子绝对重力梯度仪（图）
集成化高精度原子 重力梯度仪
2023/11/5
2022年12月7日，精密测量院詹明生研究员团队研制出集成化高精度原子绝对重力梯度仪。该重力梯度仪基于垂向层叠双原子干涉仪方案，探头体积仅为95升，测量精度达到0.86 E（1 E = 1X10-9 /s2 = 0.1 μGal/m），是目前国际上集成度最高的亚E水平的原子重力梯度仪。同时，团队完成了该梯度仪详尽的系统误差评估，使之成为国际上首台原子绝对重力梯度仪。相关研究成果2022年12月7日...
Ultraluminous X-ray source 1E 0953.8+6918 (M81 X-9): an intermediate-mass black hole candidate and its environs
