In our recent experiments, we have been studying a three-component Fermi gas with large scattering lengths. This system can serve as a simplistic model for QCD physics. Unfortunately, the stability of the three-component gas is limited in free space. However, there have been proposals on how to overcome this problem. For instance, the application of an optical lattice can improve the stability of the system drastically [1]. On the poster we present our progress setting up a new apparatus for these kind of experiments. We will use fermionic lithium in a 2D optical lattice. To achieve the necessary trapping and cooling of the atoms, we plan to use established components like a Zeeman slower, a magneto-optical trap as well as an optical dipole trap to cool the atoms to degeneracy. Additionally, there will be more advanced techniques for integrating and loading the optical lattice. A sophisticated imaging system will be needed to observe the atoms in our system.
