摘要

We have proposed a model of periodic axial magnetized hollow tube for atom guidance (1999 Opt. Commun. 16072-4). In the present paper, an analytic solution of the magnetic field inside the tube is obtained and the transportefficiency of the cold atoms in the magnetic tube at different tube intensities of magnetization is discussed. The effectof the curvature of magnetic tube on the atom transport efficiency is also considered. We have found that the tube hasa cooling effect on the transverse temperature of the transported atoms.
