More Information
Summary:The invention belongs to the field of quantum precision measurement, and discloses an optical pumping atomic beam device based on bent four conductors, which comprises a vacuum cavity, and a magnetic shielding cavity, a beam source device, a bent four-conductor static magnetic field generation structure, a microwave cavity and a fluorescence collection device which are arranged in the vacuum cavity, the bent four-conductor static magnetic field generation structure comprises four conductors with the same shape and size, and the four conductors are symmetrically arranged by taking an atomic beam as a central axis; the middle of the conductor is straight; four intersection points of any plane perpendicular to the atomic beam and the four conductors form four vertexes of a rectangle, and the length-width ratios of the rectangles are equal. According to the invention, better static magnetic field uniformity is realized in a limited space, and atomic transition frequency deviation caused by non-uniformity of the s
