Abstract
A method of simulating the evaporative cooling of neutral atoms in a magnetic trap
is presented. The method is based on kinetic theory and an assumption of ergodicity.
An application of this method to the experimental conditions in the Utrecht BEC
experiment is compared to measurements. The simulation is found to be accurate
down to a temperature of 10 microkelvin. Its predictive power makes it a valuable tool in
optimizing the cooling process.
