Title Numerical Simulations of Collimator Insertions using MAFIA
Abstract This report concerns the simulation technique for longitudinal and transverse wakes, including results for some of the proposed collimator designs tested in the SLAC end station A wake-field tests. The purpose of this exercise is to verify existing simulation results and to expand the work to include the latest proposals for collimator designs. Several collimator designs including single steps to tapered structures have been simulated and the results are presented. For each of the test pieces proposed there are calculations of the transverse and longitudinal wake functions and the corresponding kick or loss factor. The angular deflection as a function of beam off set has also been calculated for a stepped collimator insertion. The total transverse kick presented to the beam is decomposed into its constituent multi-pole components and the dipole component is compared with an analytical model. The dipole kick factor is shown to be well-predicted by the analytical model.
