We create Bose-Einstein Condensates of 52Cr atoms using an all-optical procedure [1]. In this contribution, we present the methods that we have developed to combat strong inelastic collisions in a Cr-MOT and reach degeneracy. We use intense and rapid rf sweeps to time-average to zero the magnetic trapping potential experienced by metastable dark states… CONTINUE READING
