Numerical simulations versus experimental measurements of the multipaction effect

The aim of this paper is to present comparisons between numerical simulations and experimental measurements of the multipaction effect. After a brief description of this phenomenon and a presentation of the experiment to be modeled, we exposed the numerical techniques and specific methodology that we implemented in our code DEGAS. This methodology tries to provide an efficient numerical tool for the analysis and the understanding of the multipaction phenomenon. Some comparisons are shown that point out a good agreement between experimental and numerical results. The final aim of this work would be to give a help in the designing of R.F. component free from multipaction effect.
