Abstract

A new concept of the main part of multicharged ions linear accelerator (MILAC) NSC KIPT on the combined RF focusing (CRFF) basis is proposed. In CRFF acceleration and focusing of the charged particles occurs at the expense of the same accelerating field. Absence of an external focusing field sources a design and operation of the accelerator main part considerably simplifies. The construction principle of accelerating&focusing channels with CRFF is considered. The mathematical modeling findings of a beam dynamics for particles with mass-to-charge ratio of A/q=5 in the energies range of 1…9.2 МeV/u are resulted. Realization of this focusing method on a basis of an interdigital H type accelerating structure is proposed.
