RESUMO

This work presents the development and test of an experimental set-up which allows to produce a very strong slow motion atomic beam. We discuss the calculation and construction of the solenoid to compensate the Doppler effect arising during the deceleration process, vacuum chambers, the oven which produces the atomic beam and the optical system used. We have studied the Zeeman-tuned technique to slow an atomic beam of sodium atoms. A new technique to study the deceleration which Consist in monitoring the fluorescence along the deceleration path is used, which allow us a direct observation of the process.
