A hybrid mode of one- and two-surface multipactor on grooved dielectric surface

doi:10.1088/1674-1056/25/2/025203

Abstract 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< eE₀/(4π m_ef²), 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< eE₀/(4π m_ef²), both slopes may have the multipactors. The electron surface density of the multipactor discharge has a sharp increase at the length L< eE₀/(4π m_ef²).
