Generator-Invertor-Dumper System of Electron (Positron) Bunches Moving in Cold plasma for Development of Strong Accelerating Electric Field

Abstract

It is shown that high accelerating gradient can be obtained in a specially constructed system of electron (positron) bunches, moving in cold plasma,with definite density. These combined bunch systems do not generate the wake fields behind them and can pass through the plasma column in a periodic sequence. The consideration is carried out numericaly and analyticaly in one dimensional approach, (which can be applied to finite system when its transverse dimensions are larger than plasma wave length, divided by $2\pi$). The possibilities of the experimental tests by measuring the predicted energy gain are discussed on the examples of Argonne Wakefield Accelerator and induction linac with typical parameters.
