Internal heating ultra-high temperature device for generating high-collimation atomic beam

Abstract

The invention belongs to the technical field of generation of high-collimation atomic beams, and particularly relates to an internal heating ultra-high temperature device for generating high-collimation atomic beams. A vacuum cavity shell is arranged on the outer side of the body, and a flange electrode, an electric cross-core and a water cross-core are arranged at one end of the body. The water-cooling equipment is arranged in the vacuum cavity shell and consists of a water-cooling inner wall, a water-cooling pipeline and a water-cooling outer wall; the ceramic base is arranged in the vacuum cavity shell and is used for supporting the heater and the water cooling equipment; the heater is used for heating the crucible main body, and the crucible main body is sleeved with the heater; an atomic furnace cover is arranged at one end of the crucible main body; an emergent flange is arranged on the same side of the atomic furnace cover and at the other end of the vacuum cavity shell; the high-quality and high-purity atomic beam can be provided for a cold atom experiment system in the cold atom experiment system. And the cold atom system is used for quantum simulation. By adding an artificial standard field, the topological problem can be researched, and spin-orbit coupling of Fermi gas is realized at cold atoms.

Description

technical field [0001] The invention belongs to the technical field of generating high-collimation atomic beams, and in particular relates to an internal heating ultra-high temperature device for generating high-collimation atomic beams. Background technique [0002] At present, the ultra-high temperature device for generating pure atomic beam current is an experimental device for gasifying solid matter to generate pure atomic beam with controllable spatial distribution and density. The pure atomic beam has the characteristics of narrow velocity distribution in the direction of atomic propagation and high collimation. It has been widely used in high-resolution atomic spectroscopy, atomic dynamics, and quantum control measurements. [0003] Atomic spectroscopy is a spectrum consisting of a series of light emitted or absorbed by electrons in atoms as their energy changes. The study of atomic spectroscopy is one of the important means to explore the arrangement of electrons ou...

Problems solved by technology

However, the heating power demand of external heating is large, generally directly connected with 220V voltage, the heating material is easy to oxidize when it comes into direct contact with the air, the heat preservation effect is poor, and the heat dissipation is fast. Long-term external heating may cause the flange interface part of the equipment to melt and cannot be opened. , the working life of the device is short
