It is shown that the Plasmon-X scheme used for the electron acceleration uses a sufficiently broad beam ($L_\\bot\\sim 130\\,\\,\\mu{\\rm m}$) that justifies the use of the standard stationary 1-D approximation in the electron hydrodynamic equations, since the pulse width is sufficiently bigger than the pulse length ($\\sim 7.5\\,\\,\\mu{\\rm m}$).
