a Storage Ring for Bose-Einstein Condensates

A vertically-oriented magnetic storage ring for cold atoms has been demonstrated and a Bose-Einstein condensate has been formed in a localised section of the torus. The unique magnetic coil design can be utilised as a magneto-optical trap, a Ioffe-Pritchard magnetic trap or a storage ring. The ring has a large atom number and magnetic trap lifetime compared to other rings. Additionally, its large (10cm) diameter and high level of optical access should facilitate atom interferometry.
