Paper Abstract

We investigated Ramsey resonance characteristics of the optically pumped cesium beam frequency standard constructed at KRISS. The linewidth of the Ramsey signal from a 38-cm long microwave cavity was about 260 Hz. The linewidth and peak-to-valley values of the Ramsey signal versus the microwave power were observed and compared with theoretical results obtained by taking into account the 1/v-weighted Maxwell velocity distribution in the cesium atomic beam. Both results coincided quite well, but the asymmetry in the Ramsey signal occurred, the causes of which were discussed.
