Characterization of cold atomic cloud in a magneto-optical trapud

摘要

The results of characterization of cold cloud of cesium (Cs) atoms trapped in a magneto-optical trap (MOT) have beenudpresented. The MOT is a part of the Physics package of the Cs Fountain Clock being developed at National PhysicaludLaboratory (NPL), India. The number of atoms, size and temperature of the cloud have been measured and calculated. It is also been investigated how the number of trapped atoms changes with the trapping laser’s beam intensity, detuning and magnetic-field gradient of the trap.ud
