The observed evolution of the number of atoms and temperature in the trap are consequences of the unusual trap geometry. In the present paper, we develop a model based on a set of rate equations to describe the loading dynamics of such a mechanism. We consider the collision statistics in the non-uniform trap potential that leads to twodimensional evaporation. The comparison between the resulting computations and experimental data allows to identify the dominant","authors_text":"Axel Griesmaier, Hannes Gorniaczyk, Jahn R\\\"uhrig, Markus Falkenau, Valentin V.
