Abstract :
The optically pumped Cs beam frequency standard (OPCBFS) has made great progress. Results comparable to and better than the data from the best conventional magnetic state selecting primary Cs beam frequency standard have been reported. However the light frequency shift (mainly the AC Stark shift) is a new factor affecting the frequency accuracy and frequency stability in an OPCBFS. This phenomenon has been investigated in the Cs beam tube and the results have been analysed. The results are very useful for estimating the clock frequency instability caused by the light shift
