Abstract
In this paper, detailed geometry of the detection chamber, configuration of detection probe laser beams, data acquisition and processing techniques of the cold atoms in Cs atomic fountain primary standard at NPL, India has been discussed. The S/N ratio in the detected atom count was too low to make a valid estimate of signal. By implementing an efficient design of detection hardware (especially changing photodiode with lower junction capacitance) and software, the S/N ratio in NPLI-CsF1 has been improved significantly (~ 10 times). Details of the detection hardware and software used for better processing of the signal are given in this paper. This paper also depicts the precise computer control for data processing and the improvements in signal to noise ratio in the context of fountain operation.
