We combine the Ramsey interferometry protocol, Stern-Gerlach detection scheme, and use of elongated geometry a cloud fully polarized cold cesium atoms to measure selected component magnetic-field gradient along atomic in single shot. In contrast standard method where precession two spatially separated clouds is simultaneously measured extract their phase difference, which proportional gradient,...

• The displacement control technique is used in the full maglev superconducting gravity instrument, and four-degrees-of-freedom of levitated test mass realized. Special circuits are designed to decouple detect multidegrees-of-freedom motions mass. A criterion attitude adjustment for proposed, eliminatiing mismatch coils. This great significance dynamic measurement gradiometer. Non-sensitive axi...
