摘要
A hybrid mode of one- and two-surface multipactor on the grooved dielectric surface is studied in detail using both an analytical approach and two-dimensional particle-in-cell (2D PIC) simulations. When the groove width L< eE(0)/(4 pi m(e)f(2)), there are one-surface multipactor and one-order two-surface multipactor on the grooved dielectric surface, and only one slope of the groove has the multipactor anytime. When L > eE(0)/(4 pi m(e)f(2)), both slopes may have the multipactors. The electron surface density of the multipactor discharge has a sharp increase at the length L = eE(0)/(4 pi m(e)f(2)).
