Abstract :
Our laboratory has been developing an atomic reference system in which an ensemble of cold atoms of cesium is produced already in the center of a microwave cavity. The timeline of the project is divided in three parts: proof of principle with an antenna, design of a microwave cavity with viewports to produce the magneto-optical trap (MOT) and a movable system with all the parts embedded in a single package. In this work we present the first two parts of the global project with some relevant aspects for the construction of this compact frequency standard.
