摘要: Laser-cooled neutral atoms from a low-velocity atomic source are guided via magnetic field generated between two parallel wires on glass substrate. The bend around three curves, each with 15-cm radius of curvature, while traveling along 10-cm-long track. A maximum flux 2*10^6 atoms/sec is achieved current density 3*10^4 A/cm^2 in the 100x100-micrometer-cross-section wires. kinetic energy one transverse dimension measured to be 42 microKelvin.
