An ultracold Bose-Fermi mixture of 133Cs and 6Li is an interesting system for the study of ground state polar molecules due to the large electric dipole moment as well as for the investigation of polarons because of the large mass imbalance and the tuneability of intra- and interspecies interactions. For these studies reaching a doubly degenerate quantum gas is a favourable experimental condition. We design a new cooling and trapping scheme for 6Li which combines a time averaged crossed dipole trap and gray molasses cooling, improving the starting conditions for further evaporative cooling. The enhanced phase space density of 6Li atoms allows for sympathetic cooling of 133Cs, aiming for double degeneracy.
