"Blocking" of a plasma wave by a relativistic electron bunch and its use in collective acceleration
Bazylev V. A. , Goloviznin V. V.
The excitation of wakefield oscillations by an extended bunch of relativistic electrons is analyzed. Self-consistent solitary solutions of the Bernstein-Greene-Kruskal type, for which the bunch is not slowed by the wakefield potential, are found. Substantial electric fields generated in the process are of interest for collective acceleration.
