We report an experimental realization of ultracold atoms confined in a time-averaged, adiabatic potential (TAAP). This trapping technique involves using a slowly oscillating (similar to kHz) bias field to time-average the instantaneous potential given by dressing a baremagnetic potentialwith a high-frequency (similar to MHz) magnetic field. The resultant potentials provide a convenient route to a variety of trapping geometries with tunable parameters. We demonstrate the TAAP trap in a standard time-averaged orbiting potential trap with additional Helmholtz coils for the introduction of the radio frequency dressing field. We have evaporatively cooled 5 x 10(4) atoms of Rb-87 to quantum degeneracy and observed condensate lifetimes of longer than 3 s.
