Samenvatting

The study of collisions between excited atoms requires high-intensity atomic beams to achieve detector signals of sufficient strength. Producing large densities of excited rare gas atoms R is especially difficult, since with conventional sources metastable atoms R make up a tiny fraction of ≈10-5 of the total beam flux. In such cases, 'brightening' the beam is the only way to achieve a sufficiently large flux. We have followed a scheme proposed by Metcalf to brighten an atomic beam of neon. The setup employs laser cooling on the Ne((3s)3P2 → (3p)3D3) cycling transition, and consists of three stages. First, we collimate all atoms emerging from a discharge source within a half-angle θ0 = 100 mrad. Second, the collimated beam is focused to a point. Third, the now converging beam is re-collimated to form a thin and bright atomic beam.
