A new computer code for 3D simulation of multipacting phenomenon in axisymmetric and non-axisymmetric rf structures is presented. The goal of the simulation is to determine resonant electron trajectories and electron multiplication in rf structure. Both SW and TW structures of normal- and superconductivity have been studied. Simulation results are compared with theoretical calculations and experimental measurements.

Multipactor in beam-pipe transitions of superconducting rf cavities can be explained using rf potential well theory*. In this paper we present simulation results supporting this explanation for both rf cavities and transmission lines.
