We describe a versatile and simple scheme for producing magnetically andoptically-trapped Rb-87 Bose-Einstein condensates, based on a moving-coiltransporter apparatus. The apparatus features a TOP trap that incorporates themovable quadrupole coils used for magneto-optical trapping and long-distancemagnetic transport of atomic clouds. As a stand-alone device, this trap allowsfor the stable production of condensates containing up to one million atoms. Incombination with an optical dipole trap, the TOP trap acts as a funnel forefficient loading, after which the quadrupole coils can be retracted, therebymaximizing optical access. The robustness of this scheme is illustrated byrealizing the superfluid-to-Mott insulator transition in a three-dimensionaloptical lattice.
