Title: Time-orbiting potential trap for Bose-Einstein condensate interferometry

Abstract

We describe an atom trap for Bose-Einstein condensates of {sup 87}Rb to be used in atom interferometry experiments. The trap is based on a time-orbiting potential waveguide. It supports the atoms against gravity while providing weak confinement to minimize interaction effects. We observe harmonic oscillation frequencies ({omega}{sub x},{omega}{sub y},{omega}{sub z}) as low as 2{pi}x(6.0,1.2,3.3) Hz. Up to 2x10{sup 4} condensate atoms have been loaded into the trap, at estimated temperatures as low as 850 pK. We anticipate that interferometer measurement times of 1 s or more should be achievable in this device.
