An intense clean source for cold Lithium — Tobias Tiecke, Antje Ludewig, •Sebastian Kraft, Steve Gensemer, and Jook Walraven — Van der Waals-Zeeman-Instituut, Universiteit van Amsterdam, The Netherlands
We experimentally investigate a novel atomic beam source for cold 6Li. The source operates according to the 2D-MOT principle and is found to be very monochromatic and intense. Its longitudinal velocity is centered at 33 m/s with a full-width at half maximum (FWHM) of 14 m/s, with no flux observed at higher velocities.
We measured the intensity of the source by loading a 3D MOT from the cold atomic beam. We report loading rates as high as 109 s−1 resulting in up to a total of 1010 trapped atoms.
