Abstract


We report the development, operation and characterization procedure of the first ever Cesium Atomic
Beam Clock in Pakistan. The importance of the National Time and Frequency standards is duly
highlighted in the context of a developing country. The active program spans a time of about three years
and the Ramsey Interferometric signals, i.e., the fundamental physical phenomenon, recorded recently
depict a 25 kHz broad Rabi profile incorporating a much narrower Ramsey fringe having width of about
800 Hz only clearly demonstrate a clean, smooth, stable and accurate operation of the clock.
