ABSTRACT
I. Introduction The theory of linear accelerators design was developed long ago. But, in connection with wide implementation of accelerator technology in various manufacturing processes, modem problems appear to designers. And, by our opinion, it is impossible to solve some of them through frames of traditional approaches to accelerating and focusing structw·es parameters calculations. At the present time, problems of constructing of compact, highcurrent machine with high acceleration speed and minimal losses are especially important. At this high intensity and small emittance beams with prescribed phase and energy characteristics are required.
