Abstract :
To guarantee an adequate design and a proper functionality of various machine components it is of primary importance to perform detailed studies of the charged particle transport. However, it is often not necessary to initiate individual kinetic simulations based on the discrete particle movements. When the time evolution of such integral quantities like average or rms dimensions, total energy or projected emittances is of the research interest, it is worth treating an investigated particle ensemble as a whole and applying a macroscopic formulation. Based on the moment method a fast C++ code capable to handle various beam line elements has been implemented. The present paper treats the implementation issues of the code and discusses the simulation results for such axial magnetic multipoles like quadrupoles and sextupoles under the influence of fringe field effects.
