Recently we developed a double-well magnetic trapping scheme which is a hybrid of the familiar Ioffe-Pritchard and time-averaged orbiting potential (TOP) traps. With a readily controllable barrier height and well separation this trap is a new tool for studying ultra-cold atoms, including Bose-Einstein condensates. In this talk I will describe the double-well trap, present results of evaporative cooling of rubidium, and discuss a d-wave scattering resonance in ultra-cold collisions bewteen two thermal atomic clouds.
