| Resumo | |
Resonant electron discharges (mutlipactor effects) in vacuum electronic devices are investigated through irregular-grids-based particle-in-cell (PIC) simulations. The Furman probabilistic model for the secondary electron emission (SEE) is embodied in a PIC algorithm that yields a self-consistent time update of fields and particles with charge-conserving and symplectic properties obtained from first principles. We study multipactor effects on different kinds of metal boundaries such as Cu and stainless steel and the saturation process due to a balanced competition between external RF potentials and space charges.
