We report on our experimental effort to produce heteronuclear mixtures of Rb and Cs atoms for the realization of double-species condensates and for the formation of ultracold heteronuclear molecules. The central part of our experimental setup is a glass cell which provides optimum optical access and allows rapid magnetic field switching. We have implemented a double-species Zeeman slower to simultaneously trap Rb and Cs in a magneto-optical trap. Currently we are implementing a high-power crossed beam dipole trap in order to search for interspecies Feshbach resonances and by this to determine the interspecies collision properties. Our next step will then be to produce a double condensate and to investigate double-condensate dynamics. A double condensate is also a good starting point for efficient formation of RbCs Feshbach molecules followed by the creation of an ultracold ensemble of molecules in the ro-vibrational ground state.
