Resume:
Ruan Jun, male, was born in 1980, doctor, researcher of the National Time Service Center of the Chinese Academy of Sciences. He is leading a group to develop atomic fountain clocks to keep time. The technology to improve the performance of these clocks includes laser cooling atoms, low phase noise microwave synthesize, robust laser frequency and power satabling. These clocks can be found to apply in time keeping, fundamental physics constant measurement.
Direction:
Time and frequency; Atomic fountain clock; Cold atomic physics
