Particle dynamics in an accelerating-and-focusing channel of intermediate part of a proton linac based on combined rf-focusing under following conditions: energy range 3…100 MeV, current 100 mA, and acceleration rate 5 ...

Ion beam propagation stability in an accelerating channel based on combined RF-focusing (CRFF) at high spacecharge density is investigated. It is demonstrated that in case of grouped beam acceleration, the Coulomb current ...

For high-current ion linacs operating over the medium energy range, the use of an accelerating structure that implements combined rf focusing (CRFF) is suggested. Considered is the focusing provided by short IH-, CH-, and ...
