Abstract

Highlights: We present the module for controlling the operational sequence of Cs atomic fountain. It consists of indigenously developed hardware and software aspects. Hardware deals with (RF) Radio Frequency generation to Acousto Optic Modulator (AOM). Software deals with automatic control of operational parameters of the fountain. Abstract: The sequence control system for Cs atomic fountain clock is described in this paper. An electronic module to control the operational sequence of the Cesium (Cs) fountain frequency standard has been designed and developed. This control system consists of RF generation for AOMs and provides sequential control for cyclic operation of atomic fountain. In this paper, indigenously developed hardware as well as software of the module along with the computer controlled sequence of operation of the Cs fountain is described in detail.
