Optimal Resonant Asymptotics of Wakefield Excitation in Plasma by Non-resonant Sequence of Relativistic Electron Bunches

Abstract

Resonant asymptotics of wakefield excitation in plasma by non-resonant sequence of relativistic electron bunches has been numerically simulated. It has been shown that in resonant asymptotics at optimal parameters the wakefield is excited with the maximum growth rate and the amplitude of the excited wakefield is the largest.
