RUBIDIUM ATOMIC CLOCK WITH DRIFT COMPENSATION

2011-10-19 · 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 frequency.
