| Popis: | A laboratory type cesium beam standard is being constructed for experimental use as a working standard at the RRL of Japan. Ihe structural design and experimental results on the phase adjustment of Ramsey cavity, the beam optics employing hexapole magnets, and an axial C-field, and the digital servo system are described. Methods for evaluating the beam velocity distribution employing a pulse technique and the analysis of the Ramsey pattern are examined. Observed intensity of Ramsey signal proved satisfactory, and other experiments are now proceeding. |
