Abstract

The code for multipacting simulations in axisymmetrical RF cavities, periodical structures and coaxial lines is presented. Physical model includes secondary emission simulations and particle trajectory integration in realistic RF fields. The code calculates multipactor voltage levels and discharge distribution. The paper contains simulation results for 180 MHz cavity of INP microtron-recuperator as well as measured data for this cavity demonstrating good agreement with the calculations
