CELL RESONATOR FOR AN ATOM RESONATOR

摘要

The present invention relates to an atom resonator, as well as to a cell resonator for an atom resonator, in which an antenna is disposed around a gas cell to enable microwaves of a preset frequency band to be applied to the gas cell without loss, thereby achieving accurate atom resonance. For this purpose, the cell resonator of the present invention comprises: a cylindrical gas cell into which rubidium gas or metal atom gas is injected; a ring-shaped loop antenna fitted to the outer surface of the gas cell and disposed at the exact center of the gas cell; a feeder unit arranged at both ends of the loop antenna to apply microwaves to the antenna; an insulating member arranged to cover the loop antenna to electrically insulate the loop antenna; a heating member arranged to cover the insulating member to supply heat to the gas cell; a light detection unit disposed on one side of the heating member to detect light emitted from the gas cell; and a housing disposed outside the heating member to shield the magnetic field transmitted to the gas cell. The thus-configured cell resonator for an atom resonator enables microwaves of a preset frequency band to be applied to the gas cell without loss to achieve an accurate atom resonance, and has a reduced size and superior power efficiency.
