Abstract :
From some years our group has been investing efforts to develop a Caesium atomic fountain system to operate as a frequency standard. Our most recent results concern the observation of the first Ramsey resonance and we also performed a characterization of it. We discuss the main characteristics of our system and the improvements on planning
