Rapid generation of metastable helium Bose-Einstein condensates

Abbas, A. H; Meng, Samuel; Patil, Rohit; Ross, Jacob; Truscott, Andrew; Hodgman, Sean


We report the realization of Bose-Einstein condensation (BEC) of metastable helium atoms using an in-vacuum coil magnetic trap and a crossed-beam optical dipole trap. A quadrupole-Ioffe configuration magnetic trap made from in-vacuum hollow copper tubes provides fast switching times while generating traps with a 10-G bias, without compromising optical access. The bias enables in-trap one-dimensional Doppler cooling to be used, which is the only cooling stage between the magneto-optic trap and...[Show more]
