COMPUTATION OF RESISTIVE WALL WAKEFIELDS WITH THE PBCI CODE

Wakefield effects due to arbitrary 3D geometries can be estimated with the Parallel Beam Cavity Interaction (PBCI), a parallelized and dispersion-free code. However, resistive wall losses may also have a significant effect on the beam line impedance. The contribution of this work is to incorporate these losses into PBCI simulations using wide band surface-impedance boundary conditions. The developed models are validated by convergence studies and by wakefield simulations with selected test structures
