Description
technical field [0001] The invention relates to an ultra-high vacuum system, in particular to an ultra-high vacuum acquisition system and method for experimentally preparing ultra-cold atoms and molecules. Background technique [0002] When carrying out the experimental preparation of ultracold atoms and molecules, the preparation process must be carried out in an ultra-high vacuum system. However, in practical applications, the existing ultra-high vacuum system generally has the problem that the vacuum degree is not high enough due to the limitation of its own principle. The lifetime in the magneto-optical trap is shorter, resulting in poorer fabrication. Based on this, it is necessary to invent an ultra-high vacuum acquisition system and method for the experimental preparation of ultra-cold atoms and molecules, so as to solve the problem that the vacuum degree of the existing ultra-high vacuum system is not high enough. Contents of the invention [0003] In order to so...
