Embodiment Construction

[0017] Atomic beam interferometer of the present invention such as figure 2 , as shown in FIG. 3 , including an atomic beam source 1 , a zone plate 5 , a pinhole diaphragm 6 , and a receiver 7 . where atomic beam source 1 is a metastable state 1S 3 Ne * Atom source, metastable state Ne in this embodiment * 1S 3 obtained by laser excitation ,As shown in Figure 3. The vacuum chamber 9 in the shell 8 adopts 3 mechanical pumps and 3 diffusion pumps, which can make the vacuum in the vacuum chamber 9 reach 5×10 -6 τ, the atomic free path at this time reaches more than 10 meters.

[0018] The magneto-optical trap contained in the atomic beam source 1 is composed of laser field and magnetic field, which can cool and trap atoms. Because of its simple structure, it has been widely used as a basic tool for cold atomic beam experiments for many years.

[0019] The magneto-optical trap is to use circularly polarized light to produce optical glue, tune the frequency of the ligh...

Abstract

An atomatic beam interferometer is composed of casing, vacuum cavity, atomatic beam source in the vacuum cavity, atomatic beam receiver, waveband plate between atomatic beam source and said receiver, orifice diaphragm, object to be tested and computer connected with output of said receiver. Its advantages include simple structure, high interference efficiency and high sensitivity (improved by 7 orders of magnitude).

Description

technical field [0001] The invention belongs to an atomic beam interferometer. Background technique [0002] In recent years, atomic optics has become a new subject, and the reflection, focusing, imaging, diffraction, and interference of atoms have been successfully achieved in many experiments. In particular, the research on atomic beam interferometer has gained widespread attention. According to De Broglie's principle, the wavelength of an atom depends on its speed, which is inversely proportional to its mass. The mass of atoms is much larger than that of electrons and neutrons, so the de Broglie wavelength of atoms is much smaller than that of neutrons and electrons, which will greatly improve the test accuracy. [0003] Electron and neutron interferometers are known to have been realized long ago. However, atoms are not controlled by electromagnetic fields because they have no charges; they cannot penetrate solids like neutrons, and cannot use lattice diffraction to s...
