Design and simulation of a novel magneto-optic trap

In order to study ultracold gases by photoionization within a Reaction Microscope (ReMi), we investigate a new magneto-optical trap (MOT) configuration for cooling and trapping the atoms. Here we present the simulation results. In comparison with the conventional MOT, the new MOT has four laser beam axes. Two radial laser beam axes along x and y directions and two laser beam axes inclined +/- 45 degrees to the MOT/Feshbach coil axis (z axis).
