A magneto-optical trap loaded from a pyramidal funnel.
We have demonstrated the transfer of 39 K and 40 K atoms from a magneto-optical funnel (a hollow pyramidal mirror) through a low (0:05 l/s) conductance hole and into a conventional magneto-optical trap (mot) 35 cm away, with an efficiency of approximately six percent. This simple scheme should be useful for experiments requiring high loading rates with minimal contamination from hot untrapped atoms.
