Embodiment Construction

[0035] The present invention will be further described below in conjunction with embodiment and accompanying drawing, but should not limit protection scope of the present invention with this.

[0036] refer to figure 1 . figure 1It is an explosion diagram of an integrated universal cold atom science experiment cavity. The system is mainly divided into four parts as shown in the figure. The upper and lower optical mounting disks 1, the coil cover 2, the magnetic field coil 3 and the regular twelve-sided cylindrical ultra-high vacuum chamber 4. Wherein the positive dodecagonal cylindrical ultra-high vacuum chamber 4 is the installation main body, and the upper and lower optical mounting plates fall on the periphery of the optical introduction window 17 on the upper and lower surfaces of the cavity. In the annular notch 20 on the upper and lower surfaces of the side cylinder shaped cavity. The regular octagonal vacuum flanges 18, 19 on the left and right sides are used to c...

Abstract

The invention discloses a brand-new integrated general scientific cold atom experiment cavity. The brand-new integrated general scientific cold atom experiment cavity comprises a vacuum cavity, an optical mounting disc and a magnetic field coil assembly. The integrated general scientific cold atom experiment cavity is comprehensive in function and provided with 24 optical windows; magnetic field coils of the experiment cavity are variable in direction, so a large gradient range, a large magnetic field coil with a one-way strong magnetic field and a fast-changing coil capable of achieving fast scanning can be provided, the requirements of cooling, detection and imaging during ultra-cold atom experiments and various scientific experiments on optical traps can be met, the light passing requirements of all the common optical lattice lasers of cold and ultra-cold atoms such as one-dimensional atoms, two-dimensional atoms, three-dimensional atoms, hexagonal atoms, triangular atoms and the like at present are met, and the requirements of corresponding magnetic fields are met. As a carrier for scientific experiments, the brand-new integrated general scientific cold atom experiment cavity of the invention provides a solution for a physical experiment engineering system of cold atoms.

Description

technical field [0001] The invention relates to the fields of laser cooling, atomic physics, and ultra-high vacuum, especially a device mainly used for cold atom experiments. Background technique [0002] Ultracold atomic physics represented by Bose-Einstein condensation (BEC) is an emerging scientific field that has flourished in the past decade. With the current development momentum, it can be predicted that it will remain one of the most frontier, most attractive and most dynamic fields in physics in the next two decades. The important position of this emerging field in the history of the development of physics and science and technology is self-evident. This field and related fields are due to the laser cooling of atoms (1997), the realization of Bose-Einstein condensation (2001) As well as the quantum coherence of light and the development of precision spectroscopy (2005), as well as the atomic clock and quantum control technology based on ultra-cold atomic optical lat...
