Secondary Electron Yield Reduction in High Porosity Surfaces and Its Application for Multipactor Suppression

We investigate secondary electron yield (SEY) reduction in high porosity surfaces consisting of periodic through-holes. Using Vaughan's empirical model of SEY [1], [2], we perform two-dimensional Monte Carlo (MC) simulation [3], [4] of the electron trajectory in a single well and determine the effective SEY of a porous surface.
