Design of the high-current ion injector for ions with z/A≥1/3 is described. The system consists of a laser-plasma generator based on a repetition rate CO2 laser, a vacuum target chamber with optical focusing lens, a beam extraction and transport system, and RFQ accelerator with z/A≥1/3. The goal of the work is to optimize parameters of all of the above components for maximum ion beam current at the output. Carbon ion energy spectra of CO2 laser produced plasma at radiation power density of 8•1011 W/cm2 were studied. Conditions for generating С4+÷С6+ ions in the vacuum chamber in use were found. The С4+ ion beam produced by the source was matched into the RFQ and measurements of its emittance and current are being performed.
