A device for generating atomic vapor beams in a vacuum environment

Abstract

The invention discloses a device for generating an atom steam beam in a vacuum environment. The device for generating the atom steam bean in the vacuum environment comprises a sample and a boiler tube; one end of the boiler tube is closed and the other end of the boiler tube is open; the sample is arranged inside the boiler tube; a tungsten filament is wound on the outer wall of the boiler tube in a spiral mode; a ceramic sleeving is arranged on the boiler tube; a light shielding outer layer wraps a side part and two ends of a ceramic sleeving; an atom steam beam ejection port used inside the boiler tube is arranged on the light shielding outer layer; and the two ends of the tungsten filament go through the ceramic sleeving and the light shielding outer layer. The device for generating atom steam beam in vacuum environment can provide smaller heating current in order to reach higher temperature so as to generate atom steam beam of the needed sample. The device for generating the atom steam beam in vacuum environment can be fixed in a collimation manner in order to make the generated steam beam relatively accurately achieve the needed place, besides, can reduce the light noise.

Description

technical field [0001] The invention relates to the field of ion trapping devices, in particular to a device for generating atomic vapor beams in a vacuum environment. It is suitable for optical frequency standard, quantum optics, quantum information and other fields. Background technique [0002] In the optical frequency standard experiment, the reference physical systems mainly include the atomic system and the ion system, among which the current optical frequency standard based on the atomic system is mainly realized by referring to multiple trapped atoms in the optical lattice; while the optical frequency standard based on the ion system It is mainly implemented with reference to trapped ions. The ion system needs the ion trap to use the electromagnetic field to capture and stably trap the ions in a certain range of space, and the generation of ions is a crucial part of the ion optical frequency standard. The atomic vapor beam passes through the center of the trap, one...
