2022-12-29 Design and operation of a transportable Rb-87 atomic fountain clock doi:10.57760/sciencedb.07003 en Time of flight (TOF) signals of cold atoms in the detection zone when the interrogation microwave is locked to the atomic reference frequency before and after transportation.Ramsey pattern obtained by scanning the microwave frequency of the Ramsey cavity using 0.1-Hz steps after transportation，the line width of the central fringe is ∼1.07 Hz.Daily average of the frequency drift of the fountain clocks against hydrogen maser for three periods of time. atomic fountain clock; laser cooling; frequency reproducibility Henan Cheng Desheng Lv PUBLIC https://creativecommons.org/publicdomain/zero/1.0/ dataset Science Data Bank
