Abstract
Description
Technical Field
[0001] This invention belongs to the field of electric field control technology, specifically relating to a high-precision, interference-resistant, uniform electric field generating device. Background Technology
[0002] In experiments involving Rydberg atoms, the atoms are extremely sensitive to their surrounding electric field environment due to their enormous electric dipole moment. This sensitivity is directly manifested through the Stark effect: the interaction between the external electric field and the atomic dipole moment leads to the shift and broadening of the atomic energy levels. Rydberg states with high principal quantum numbers (n) possess extremely high polarizability, so even a weak electrostatic field can induce significant energy level shifts.
[0003] To address these issues, conventional experimental setups typically employ electric field shielding in a non-vacuum environment. However, in such environments, air contamination on the electrode surface can cause unstable contact potentials and charge fluctuations. These stray electric fields affect the electric field strength at the locations of Rydberg atoms, leading to Stark shifts in the Rydberg atomic energy levels. This results in resonance frequency drift and broadening, making experimental signals unclear or even unobservable. Furthermore, changes in ambient temperature and humidity continuously alter the surface adsorption state and stray electric field modes, causing experimental results to be unreproducible and significantly reducing reliability.
[0004] In summary, placing the shielding device outside of a vacuum atmosphere will cause it to lose its shielding effectiveness, thereby introducing uncontrollable noise and ultimately having an adverse effect on Rydberg state atoms. Summary of the Invention
[0005] This invention addresses the problem that existing technologies cannot meet experimental requirements due to external interference by providing a high-precision, interference-resistant, uniform electric field generating device.
[0006] To achieve the above objectives, the present invention employs the following technical solution: A high-precision, interference-resistant uniform electric field generating device includes an octagonal cavity, a fixed base is embedded in the lower end of the octagonal cavity, the octagonal cavity and the fixed base are fixed by bolts, four electrode components are arranged on the fixed base, the four electrode components are grouped in pairs, the electrode components are connected to the fixed base by fasteners, and the electrode components are arranged inside the octagonal cavity. The electrode component includes a pure titanium rod, the upper end of which is fixed with an electrode mounting plate by bolts. The electrode mounting plate is plated with four electrode plates, the contacts of which extend to the end of the electrode mounting plate and are connected by wires along the pure titanium rod to the outside of the octagonal cavity. The electrode plates are made of pure gold. The pure titanium rod is connected to the housing by a fastener. The electrode mounting plate is located at the upper end inside the octagonal cavity.
[0007] Furthermore, the octagonal cavity includes an octagonal outer shell, the outer wall of which is in the shape of a regular octagonal prism. Each prism has a light-transmitting hole on its side end face. A hollow cylindrical glass tube is fixedly installed on one of the light-transmitting holes, and glass substrates are fixedly installed on the other light-transmitting holes. Anti-reflection films of different wavelengths are coated on the glass substrates respectively. A flange is fixedly installed at the lower end of the hollow cylindrical glass tube. A correction groove is provided on the lower end face of the flange, and a fixing seat is provided inside the flange.
[0008] Furthermore, the fixing base includes a housing, the lower end of which is provided with four positioning holes, which are evenly distributed in a circular array with the center of the housing as the center point. The lower end face of the housing is provided with a second correction groove, which corresponds to the first correction groove. The outer surface of the housing is provided with mounting holes. The housing is fixed to the flange by positioning hole bolts. The fixing base is made of pure titanium.

[0013] 2. The device of this invention employs four electrode mounting plates, with four electrode plates fixed on each plate.

By utilizing the property that pure titanium does not release gas at high temperatures that would affect the vacuum, the accuracy of the experimental results and the stability of the experimental apparatus are ensured.
