COMPARATIVE ANALYSIS OF ACCELERATION OF TEST ELECTRON BUNCH BY TRAIN OF BUNCHES IN THE DIELECTRICAL WAVEGUIDE AND RESONATOR FILLED WITH PLASMA

Results of numerical simulation of acceleration of test bunch by sequence of relativistic electron bunches in the dielectrical cylindric slowing-down structure filled with plasma for the cases opened and closed by the conductive grid of output end face of structure are provided. The entrance end face has been closed by the conductive grid. The initial sizes and energy of all bunches were identical. The distance between bunches of sequence is equal to the wavelength of electromagnetic field in the structure. The test bunch followed the last bunch of the sequence. Acceleration of test bunch at changing of number of drive bunches in a sequence was investigated. We have found out that at certain number of bunches in the resonator it is possible to obtain significantly greater acceleration, than in waveguide.
