Dynamics Analysis of Particles in Coaxial Lines Loaded Ceramic window

Multipacting is electron discharge that occurs in components where operate with RF high-power electromagnetic fields. In this paper, we will study the motion characteristics of particles in the coaxial structure with a ceramic window. A Monte Carlo algorithm is used to track the secondary electron trajectories and study the multipactor scenario on the surface of a ceramic window by using 2-D particles trajectory code. By studying the motion of particles, we can provide guidance for suppressing secondary electron multiplication in coaxial waveguide loaded ceramic.
