简介
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× 10 6 atoms/sec is achieved with a current density of 3× 10 4 A/cm 2 in the 100× 100-μ m-cross-section wires. The kinetic energy of the guided atoms in one transverse dimension is measured to be 42 μ K.
