    "abstract": "We present a 2D-MOT setup for the production of a continuous collimated beam\nof cold 87-Rb atoms out of a vapor cell. The underlying physics is purely\ntwo-dimensional cooling and trapping, which allows for a high flux of up to\n6*10^(10) atoms/s and a small divergence of the resulting beam. We analyze the\nvelocity distribution of the 2D-MOT. The longitudinal velocity distribution of\nthe atomic beam shows a broad feature(FWHM=75m/s), centered around 50m/s. The\ndependence of the flux on laser intensity, geometry of the trapping volume and\non pressure in the vapor cell was investigated in detail. The influence of the\ngeometry of the 2D-MOT on the mean velocity of the cold beam has been studied.\nWe present a simple model for the velocity distribution of the flux based on\nrate equations describing the general dependencies.",
