We report the improvement of the frequency stability of a small sized optically pumped Cs beam clock Cs4. This is essentially due to the increase of the signal to noise ratio through detection with a cycling transition. Pumping and detection are respectively performed by means of the (F=4 /spl rarr/ F'=4) and (F=4 /spl rarr/ F'=5) transitions of the Cs D2 line. An excellent frequency stability ...
