The China Academy of Engineering Physics (CAEP) plans to build XFEL light source. In the beam dynamics simulation there are many parameters to be considered, so we need a high efficient method to find the optimal pa-rameters. Genetic algorithm (GA) [1] is wildly used as one kind of evolutionary algorithm and it can help us to find the optimal parameters in a shorter time. In this paper, we will use genetic algorithm to do the beam dynamics sim-ulation of an L-band electron gun used for the XFEL. We put emphasis on the optimization of the transverse nor-malized projected emittance and the relevant result will be given and discussed.
