Abstract
In the present paper, the development of an electronic module for controlling the atomic flux from Cesium (Cs) Source (Cs ampoule) to the cooling chamber of Physics package of Cs fountain clock being developed at National Physical Laboratory (NPL) India, is described. Cs source is integrated with octagonal cooling chamber and the amount of Cs diffusing into the chamber is controlled by controlling the temperature of Cs ampoule. The atomic flux controller is basically a temperature controller which is designed for maintaining the temperature from 10 degrees C to 80 degrees C. It is based on lockin amplifier and proportional-integral-differential (PID) controller techniques for precise control of temperature. We have used Thermoelectric Coolers (TECs) for cooling and heating the Cs ampoule.
