Abstract
An optically pumped atomic beam apparatus based on curved four conductors includes a vacuum chamber; and a magnetic shielding chamber, a beam source device, a curved four-conductor static magnetic field generation structure, a microwave cavity, and a fluorescence collection device are disposed in the vacuum chamber. The curved four-conductor static magnetic field generation structure is composed of the curved four conductors with same shapes and sizes, and the curved four conductors are symmetrically arranged by taking an atomic beam as a center axis; a middle portion of each of the curved four conductors is a straight section, and two end portions of each of the curved four conductors are two curved sections bent towards the atomic beam; and a rectangle is formed by intersecting any plane perpendicular to the atomic beam with the curved four conductors, and a length-width ratio of each rectangle is the same.
