We describe a novel atom trap for Bose-Einstein condensates of 87Rb to beused in atom interferometry experiments. The trap is based on a time-orbitingpotential waveguide. It supports the atoms against gravity while providing weakconfinement to minimize interaction effects. We observe harmonic oscillationfrequencies omega_x, omega_y, omega_z as low as 2 pi times (6.0,1.2,3.3) Hz. Upto 2 times 10^4 condensate atoms have been loaded into the trap, at estimatedtemperatures as low as 850 pK. We anticipate that interferometer measurementtimes of 1 s or more should be achievable in this device.
