In order to study surfaces or to make reaction on a surface at a precise position, we need to create electrons beams of few eVs with high brightness: focused on a tiny spot and with a low energy. The purpose is to connect our experiment with Anne Lafosse's experiment at Orsay (see her talk) in which the team uses intense electron beam but on a spot of several mm. With our experiment, we should have an electron beam 1000 times better in terms of current dentity and of focusing size. This talk will present how a 2D-Magneto Optical Trap (MOT) can create such a beam.

Our experiment is based on a 2D-MOT. We cool Cs atoms in 2 dimensions. On the last dimension we apply a pushing beam to accelerate the atoms in a specific direction and create a continuous atomic beam with a high flux near  atoms per second. With this flux, it is possible to create ~1 nA electron beams. A study on the power, the shape and the wavelength of the pushing beam has been achieved to control the flux of atoms in the ionization area. Permanents magnets can also be added to create a magnetic field gradient and compress the atomic beam and control the flux of atoms in the ionization area.
