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 MeV/m, is studied. To implement combined rf-focusing, it is proposed to use accelerating structures of two different types: an Interdigital IH-type structure allows acceleration in the range of 3 to 20 MeV, while a Crossbar CHtype structure accelerates particles from 20 up to 100 MeV. Also, methods to adjust rf-field amplitude in quadrupole gaps for both (IH and CH) structures are discussed.
