The new prestripping section of the heavy ions linear accelerator with mass-to-charge ratio A/q ≤ 20, allowing to accelerate ions from 6 keV/u to energy of 1 MeV/u is developed. The section represents a combination of diverse accelerating structures in one сavity: with radio frequency quadrupole focusing (RFQ) and structure with drift tubes (DTL). In contrast to conventional acceleration systems, the use of the more compact hybrid сavity simplifies system operation due to their coupled complex acceleration electrode and integrated peripheral devices, such as their power and vacuum systems. However thus distribution RF-field in such structure and its frequency characteristics essentially changes. It is shown that using tuning devices: tuners, end resonant, inductive and capacitive elements in such structure it is possible to provide require frequency and uniform distribution of electric field in an accelerating path of the hybrid сavity.
