We started a new experiment for the production of ultracold fermionic quantum gases and Bose-Fermi mixtures. The production scheme is based on loading of a multiple-species magneto-optical trap (MOT) with fermionic lithium from a Zeeman slower and fermionic potassium as well as bosonic rubidium from vapor dispensers. In a next step, the atoms will be magnetically trapped and transferred [1] from the MOT chamber into a UHV chamber, where the fermions will be sympathetically cooled by rubidium. We present the status of the experiment and show experimental results on the simultaneous magneto-optical trapping of ⁶Li, ⁴⁰K, and ⁸⁷Rb. Furthermore, we relate to applications for non-interacting fermions and for two-component fermionic quantum gases in the strongly interacting regime.
