Abstract :
An optically pumped cesium beam resonator that allows the optimization of the interaction processes among three magnetic regions has been designed. It is demonstrated that such an optically pumped cesium beam resonator can be operated at low C-field value without any loss of optical pumping efficiency. This shows that the optical pumping technique is able to improve the long-term frequency stability as well as the short-term frequency stability
