Rubidium atomic clocks are not primary standards because their frequencies change in time due to internal and external influence sources. The main one is the buffer gas they have, necessary for the operation. This gas reduces the velocity of the rubidium molecules, reducing the internal noise but the variation of its content changes the output
atomic clocks, in particular the capabilities of small, low-power, rubidium vapor-cell clocks. How the vapor-cell clock came to play such an important role in modern timekeeping is a story that goes back half a century, and one that high-lights the close interplay between basic science and techno-logical innovation. The vapor-cell atomic clock
