Honors & Achievements
 Rubidium 87 fountain clock has run continuously, with short-term stability of 2.E-τ-1/2, long-term stability of 8E-16@50 000s, and uncertainty of 1.8E-15;
 A rubidium 85 fountain clock has been build up, physical and microwave experiments has finished, with atomic number of 106, atomic temperature of 4μK, and Ramsey linewidth of 1Hz;
 Series experiments of magnetic field measurements, including the method of magnetic field measurement by the weak magnetic-sensitive Zeeman splitting, the method for measuring the magnetic field vector by probing the line strength of stimulated Raman transitions, and a dynamical compensation method to smooth the spatial fluctuation of the magnetic field in the fountain clock;
 Researches on noise of atomic clock, A real-time noise distinguish operation of atomic clocks improves the statistical uncertainty by about an order of magnitude of our fountain clock which is deteriorated previously by extra noises.
