Abstract:
     A field-moving space cooling atom clock applied to the upper air frequency standard, including an atom capturing cavity with atom source, a vacuum guide tube, a microwave resonant cavity, a magnetic shield, a thermostatic cover, a solenoidal coil, a detecting cavity, a vacuum bump system, a computer, a microwave generator, a laser system and a bracket. The characteristics are: adopt a movable microwave resonant cavity to complete the atom selection and the mutual function of the atom and the microwave. This invention can eliminate the end-to-end phasic error brought by the resonant cavity, simplifies the structure and improve the precision of the cooling atom clock.
