Va. Balakirev et al., ACCELERATION OF ELECTRONS BY A TRAIN OF RELATIVISTIC-ELECTRON BUNCHESWITH AN ALTERNATING REPETITION RATE IN A PLASMA, Plasma physics reports, 22(7), 1996, pp. 573-575
The excitation of wake fields by a train of electron bunches with a de
creasing repetition rate in a plasma is studied by means of a self-con
sistent approach. It is shown that the wake wave excited by the preced
ing bunches traps the succeeding ones and prevents their spreading in
phase space. The acceleration of relativistic electrons by the excited
wake field is investigated.
