Embodiment

[0017] figure 1 As shown, the cesium beam tube of the present invention is arranged inside the casing 1, and the cesium beam tube is mainly composed of a cesium beam path tube 4, a transition section 6, a collimator 7, a cesium absorption bubble 9, a cesium furnace 8 and a cesium bubble 2 constitute. The cesium absorbing bubble 9 is sealedly connected to one end of the cesium beam path tube 4 , and the interior of the cesium absorbing bubble 9 is also communicated with the interior of the cesium beam path tube 4 . The transition section 6 is made of a metal material with an expansion coefficient close to that of glass. In order to ensure a high vacuum seal, the transition section 6 is hermetically connected to the other end of the cesium beam path tube 4. At the same time, it is made of corrosion-resistant materials. The completed collimator 7 is sealed with the transition section 6 by means of argon arc welding.

[0018] The cesium furnace 8 is directly matched and sealed w...

Abstract

The invention discloses a cesium-beam tube based on a glass structure, which mainly comprises a cesium-beam path tube (4) and a cesium absorption bulb (9) that is connected with one end of the cesium-beam path tube (4) in a sealing way, and the cesium-beam tube is characterized in that: the other end of the cesium-beam path tube (4) is connected with a transition section (6) in a sealing way, andthe transition section (6) is connected with a collimator (7) in a sealing way and a cesium furnace (8) which is connected with the collimator (7) in a sealing way; simultaneously, the cesium furnace(8) is internally provided with a cesium bulb (2); and the cesium furnace (8), the cesium bulb (2), the cesium absorption bulb (9) and the cesium-beam path tube (4) are all made of glass. The glass cesium-beam path tube, the transition section and the cesium bulb are all made of glass instead of metal materials, thus greatly reducing the requirements on the manufacturing process and the manufacturing cost.

Description

technical field [0001] The present invention relates to a cesium beam tube, in particular to a cesium beam tube based on a glass structure. Background technique [0002] At present, the optically pumped small cesium clock has a wide range of applications in time unification, punctuality, navigation and communication systems, and its core device, the cesium beam tube, plays a decisive role in the performance of the entire optically pumped small cesium clock. [0003] Although the cesium beam tube of the traditional optically pumped small cesium clock can basically meet the requirements of people's use, it still has the following defects: 1. Since the cesium beam tube of the traditional optically pumped small cesium clock is completely made of metal materials, so Its overall weight is heavy and the volume is large, which is not conducive to installation and carrying; 2. The cesium beam path, U-shaped cavity, cesium furnace, C field coil and magnetic shielding layer in the trad...
