Problems solved by technology

[0007] (2) The adsorption pump is arranged in a ring shape, which is sleeved on the periphery of the neck channel. The ring-shaped middle structure makes the volume of the adsorption pump large, which is not conducive to the miniaturization of the hydrogen atom maser
[0008] (3) The ring-shaped adsorption pump is sleeved on the neck channel. If the adsorbent deteriorates or is damaged, the adsorbent cannot be replaced. Several times or even dozens of times the amount of adsorbent is required, resulting in a further increase in the volume and weight of the adsorption pump

Abstract

The invention discloses a vacuum maintaining device for a hydrogen atom laser, which comprises a neck channel arranged between an ionization bubble and an atom storage bubble, at least one adsorption pump and an ion pump, the ion pump is communicated with the adsorption pump, and the vacuum maintaining device is characterized in that the number of the adsorption pump is at least one; and each adsorption pump is arranged on the side edge of the neck channel and is independently communicated with the neck channel. According to the technical scheme, when the adsorbent is baked, activated and heated, a very complex cooling circulation system is not needed to cool the ionization bubble, the state selection magnet and the nearby shell, a large amount of heat energy is prevented from being transmitted to the ionization bubble, the state selection magnet and other components, and the vacuum failure of the hydrogen atom laser or the magnetic loss of the state selection magnet is avoided. And the adsorption pump is not sleeved on the neck channel any more, so that the volume structure is more compact, and the volume and the weight of the adsorption pump are greatly reduced. And after the valve and the flange are additionally arranged on the adsorption pump, the adsorption pump can be conveniently backed up, disassembled and assembled under the condition that the vacuum environment of the hydrogen atom laser is not damaged, and the service life of the hydrogen atom laser is effectively prolonged.

Description

technical field [0001] The present application relates to the field of hydrogen atom masers, and in particular, to a vacuum maintenance device for hydrogen atom masers and a hydrogen atom maser. Background technique [0002] Time frequency is the most precise and accurate quantity that can be measured in physical quantities at present. The hydrogen atom maser uses the two hyperfine magnetic energy levels of hydrogen atoms (F=1, m F =0 state to F=0, m F =0 state) to operate the time-frequency reference. Studies have shown that factors such as hydrogen atom spin-exchange relaxation and collisions between hydrogen atoms and other stray gases will seriously affect the performance indicators of hydrogen atom masers. High vacuum requirements, preferably maintained at 10 -5 ~10 -6 above the magnitude of pa. [0003] The physical part of the hydrogen atom maser mainly includes a hydrogen atom beam source 1, a state-selective magnet 2, an atomic storage bubble 3, a microwave res...
