Compact frequency standard with cold atoms

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.
