Abstract :
An experimental miniaturised rubidium frequency source which has been built in a volume of a little more than 100 in3 provides a stability of better than 1 part in 108 over one year and a warm-up time of 5 min. This long-term stability lies between that of a good crystal frequency standard and a high-grade rubidium atomic frequency standard.
