Implementation of the beam reversal technique on compact cesium clocks: towards an improvement in accuracy

Reports the evaluation of the residual phase difference /spl utri//spl phi/ in a short (18 cm) Ramsey cavity by implementing the beam reversal technique in an optically pumped cesium beam clock. /spl utri//spl phi/ is measured to be 21 /spl plusmn/1.5 /spl mu/rad, allowing a more accurate evaluation...

Description
Summary:Reports the evaluation of the residual phase difference /spl utri//spl phi/ in a short (18 cm) Ramsey cavity by implementing the beam reversal technique in an optically pumped cesium beam clock. /spl utri//spl phi/ is measured to be 21 /spl plusmn/1.5 /spl mu/rad, allowing a more accurate evaluation of the frequency performance of this small cesium clock. Finally, the clock accuracy is equal to 1.1/spl middot/10/sup -13/.
