MICROWAVE RAMSEY PATTERN IN A LASER PUMPED CESIUM BEAM. APPLICATION TO VELOCITY DISTRIBUTION AND 2nd ORDER DOPPLER-SHIFT IN FREQUENCY STANDARD
M. ArditiInstitut d'Electronique Fondamentale, 91405 Orsay, France
Abstract
Analysis of experimental microwave Ramsey patterns, obtained with a laser pumped cesium beam frequency standard, shows the cesium atoms velocities to follow a broad Maxwellian distribution. As a consequence, the estimate of the second-order Döppler-shift and cavity phase-shift could be more accurately obtained with this device than with the classical cesium beam frequency standard.
