ATOMIC FREQUENCY STANDARD Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: atomic frequency standard includes heating winding arranged around shell which limits microwave cavity resonator. Winding is designed to supply heat to absorption cell located in resonator. Absorption cell is embraced by electrodes intended to improve and orient magnetic oscillatory field near absorption cell. Heat conducting units join electrodes to shell of resonance cavity to ensure best temperature control for cell with maintenance of advantages provided by electrodes. EFFECT: enhanced functional reliability and stability of standard. 18 cl, 3 dwg
