Abstract
RODRIGUEZ Y MASEGOSA, R.; MOYA-CESSA, H. and CHAVEZ-CERDA, S.. Doughnut shape atom traps with arbitrary inclination. Rev. mex. fis. [online]. 2006, vol.52, n.1, pp.80-84. ISSN 0035-001X.
Since the invention of magneto-optical trap (MOT), there have been several experimental and theoretical studies of the density distribution in these devices. To the best of our knowledge, only horizontal orbital traps have been observed, perpendicular to the coil axis. In this work we report the observation of distributions of trapped atoms in pure circular orbits without a nucleus whose orbital plane is tilted up to 90° with respect to the horizontal plane. We have used a stabilized time phase optical array in our experiments and conventional equipment used for MOT.
