Abstract
Electrons cavity acceleration is one the relativistic regime to describe the monoenergetic electron acceleration. In this work, we introduce a new ellipsoid model that could be improved the quality of the electron beam in contrast to other methods such as that using periodic plasma wake field, spherical cavity regime and plasma channel guided acceleration. The trajectory of the electron motion can be described as hyperbola, parabola or ellipsoid path. It is influenced by the position and energy of the electrons and the electrostatic potential of the cavity. We have noticed that the electron output energy is not affected by the elongation of the transverse cavity radius in the ellipsoid regime.
