Laser-cooled neutral atoms from a low-velocity atomic source are guided via a magnetic field generated between two parallel wires on a glass substrate. The atoms bend around three curves, each with a 15-cm radius of curvature, while traveling along a 10-cm-long track. A maximum flux of 2×106 atoms/sec is achieved with a current density of 3×104 A/cm2 in the 100×100- μm-cross-section wires. The kinetic energy of the guided atoms in one transverse dimension is measured to be 42μK.
