ZEEMAN-SLOWER, COIL FOR A ZEEMAN-SLOWER DEVICE AND A METHOD FOR COOLING AN ATOM BEAM

摘要

The present invention relates to a Zeeman-slower device, to a coil for such a Zeeman-slower device and to a method for cooling an atom beam. A Zeeman-slower is disclosed having a cooling section (212) comprising an inner passage (230) extending along a longitudinal axis (L), the inner passage (230) having a cross-section perpendicular to the longitudinal axis (L), wherein the area of the cross-section of the inner passage (230) increases monotonously along the longitudinal axis (L) at least in a part of the cooling section (212).
