Rubidium atomic frequency standard microwave cavity resonator

Abstract

This invention discloses a rubidium atomic frequency standard microwave resonant cavity, which is composed of the resonant ring, support tube, cylindrical cavity, rubidium absorption foam, rubidium filter foam, heating pipe, heating pipe block, C coil, and etc. The rubidium absorption and filter foam insert into the support tube, the media ring inserts into the position between the support tube and cylindrical cavity, the resonant ring inserts into the position between the media ring and rubidium absorption foam, the cylindrical cavity sets out of the media ring linking the support tube by screws, the heating triode sets in the heating tube block, and the block links the support tube and cylindrical cavity through screws.

Description

technical field [0001] The invention relates to the field of a rubidium atomic frequency standard microwave resonant cavity, and more specifically relates to a rubidium atomic frequency standard microwave resonant cavity, which can be directly used in the rubidium atomic frequency standard. Background technique [0002] With the development of modern technology, more stable and precise time-frequency signals are required in many fields, and traditional mechanical timing and crystal oscillator timing can no longer meet the needs. The atomic frequency standard has extremely high stability and accuracy, so it has been used more and more widely. Among them, the rubidium atomic frequency standard is small in size, light in weight and good in performance, so it occupies a large market share. [0003] The rubidium atomic frequency standard consists of a physical part and a circuit part. The physical part determines the main performance of the rubidium atomic frequency standard. ...
