Abstract
We describe the current state of progress of the Cesium fountain frequency standard development at the National Physical Laboratory India (NPLI). The optical set-up of the fountain needed to capture, cool, manipulate and detect the cesium atoms is discussed in detail. The concept and design of physical structure of the fountain is also described. In addition, some of the recent results on cooling and trapping of cesium atoms are reported.
