The results from theoretical and experimental studies, as well as
from 2.5-dimensional (2.5-D) numerical simulation of plasma wake field
excitation, by either relativistic electron bunch, laser pulse, and the
charged particle wake field acceleration are discussed. The results of
these investigations make it possible to evaluate the potentialities of
the wake field acceleration method and to analyze whether it can serve
as a basis for creating a new generation of devices capable of charged
particle accelerating at substantially higher (on the order of two to
three magnitudes) rates in comparison with those achievable in
classical linear high-frequency (resonant) accelerators.
