Analysis of ultrashort accelerated electron beam using the short-range monopole wake fields driven by the beam during its penetration in the drift tube of the laser-driven rf electron gun

摘要

We investigate theoretically the influence on the beam quality of the short-range monopole wake fields caused by an accelerated electron beam during its penetration in the drift tube of the laser-driven radio-frequency electron gun, as measured by the whole-beam emittances: longitudinal and radial, as well as by energy loss.
