We demonstrate experimentally the continuous and pulsed loading of a slow and cold atomic
beam into a magnetic guide. The slow beam is produced using a vapor loaded laser trap, which ensures
two-dimensional magneto-optical trapping, as well as cooling by a moving molasses along the third
direction. It provides a continuous flux larger than 109 atoms/s with an adjustable mean velocity
ranging from 0.3 to 3 m/s, and with longitudinal and transverse temperatures smaller than
K. Up to 
atoms/s are injected into the magnetic guide and subsequently guided
over a distance of 40 cm.
