Modified quantum frequency standard on Hg-199 ions

Nikita A. Lukashev, Vadim Vladimirovich Davydov, V. Yu. Rud’

Abstract The world around us depends on devices capable of producing or maintaining a signal with an extreme precision. Quantum frequency standards are the answer to this problem. This article presents a modified version of newly developed quantum frequency standard based on trapping Hg-199 ions by magnetic field. The new prototype was developed a while ago and now it was modified due to algorithm improvements and renewed digital hardware, analog and digital circuitry being reordered. Results for Allan deviation show 3 % improvement for long-term frequency stability and more than 5 % for short-term stability

Evaluation of the frequency instability limited by Dick effect in the microwave 199 Hg + trapped-ion clock

Yi-He Chen, Lei She, Man Wang +3 more

In the microwave 199 Hg + trapped-ion clock, the frequency instability degradation caused by the Dick effect is unavoidable because of the periodical interrogating field. In this paper, the general expression of the sensitivity function g ( t ) to the frequency fluctuation of the interrogating field with Nπ -pulse ( N is odd) is derived. According to the measured phase noise of the 40.5-GHz microwave synthesizer, the Dick-effect limited Allan deviation of our 199 Hg + trapped-ion clock is worked out. The results indicate that the limited Allan deviations are about and respectively in the linear ion trap and in the two-segment extended linear ion trap under our present experimental parameters.
