Jenkin, D. McCarron, M. Köppinger, H. Cho, S. Hopkins, S. Cornish] We report an apparatus and method capable of producing Bose-Einstein condensates (BECs) of ∼1 × 106 87Rb atoms, and ultimately designed for sympathetic cooling of 133Cs and the creation of ultracold RbCs molecules. The method combines several elements: (i) the large recapture of a magnetic quadrupole trap from a magneto-optical trap; (ii) efficient forced RF evaporation in such a magnetic trap; (iii) the gain in phase-space density obtained when loading the magnetically trapped atoms into a far red-detuned optical dipole trap, and (iv) efficient evaporation to BEC within the dipole trap. We demonstrate that the system is capable of sympathetically cooling the |F = 1, m F = −1〉 and |1,0⟩ sublevels with |1, +1〉 atoms. Finally we discuss the applicability of the method to sympathetic cooling of 133Cs with 87Rb. EDP Sciences, SIF, Springer-Verlag Berlin Heidelberg, 2011 Jenkin D.
