Abstract

We report progress on an experiment on trapped metastable 4He (23S1) atoms which aims at producing a dense gas of ultra cold atoms, with the goal of reaching Bose-Einstein condensation We have built a magneto-optical trap (MOT) in which we study the cold collisions, which are the main loss cause limiting the obtainable density.
