Abstract—A review is given of theoretical and experimental investigations and numerical simulations of the
generation of intense electromagnetic fields in accelerators based on collective methods of charged particle
acceleration at rates two or three orders of magnitude higher than those in classical resonance accelerators. The
conditions are studied under which the excitation of accelerating fields by relativistic electron bunches or
intense laser radiation in a plasma is most efficient. Such factors as parametric and modulational processes, the
generation of a quasistatic magnetic field, and the acceleration of plasma electrons and ions are investigated in
order to determine the optimum conditions for the most efficient acceleration of the driven charged-particle
bunches. © 2002 MAIK “Nauka/Interperiodica”.
