Thesis- Preliminary Presentation

Cesium clocks use the hyperfine transition frequency of cesium-133 atoms to keep extremely accurate and consistent time. They work by launching cesium atoms in an atomic fountain, exposing them to microwave radiation in a cavity to induce hyperfine transitions, and detecting the absorption spectrum to determine the resonance frequency, which is used as the clock signal. Cesium clocks are the current international standard for defining the second due to their high precision and accuracy.
