Description
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 CO$_2$ laser, a vacuum target chamber with optical focusing system, 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 CO$_2$ laser produced plasma at radiation power density of $8·10^{11} W/cm^2$ were studied. Conditions for generating С$^{4+}$÷ С$^{6+}$ ions in the vacuum chamber in use were found. The С$^{4+}$ ion beam produced by the source was matched into the RFQ and measurements of its emittance and current are being performed.
