Interaction Between High-Density Beams of Charged Particles
RÉSUMÉ
Collective methods î the charged particle acceleration have attracted researchers for many years [1, 2]. Plutto and co-workers of the University of Physics and Technology (Sukhumi, Georgia) were the first to succeed in demonstration of collective acceleration of ions back in 1960s. A characteristic feature of the experiments was a comparatively low voltage applied to the plasma volume from which the ion and the electron beam were extracted. While the collective nature of the acceleration was recognized, no developed theory of the effect was suggested. Further experimental investigations of collective acceleration methods lead to the results as follows i) the energy of ions is proportional to their charge and is weakly dependent on the gas pressure; ii) the ion pulse length is almost one order of magnitude shorter than that of the electron pulse; iii) the ion pulse travels in synchronism with the electron beam pulse, which is accompanied by an increase in the energy of accelerated ions, and iv) the ion pulse intensity attainable for heavy elements is markedly lower than for hydrogen.
