Abstract: Focusing of a low-energy beam of heavy ions in a linear accelerator based on a periodic sequence of independently phased superconducting cavities is considered. The possibility of heavy ion beam focusing by a system of superconducting solenoids is analyzed. The advantages and disadvantages of this focusing technique are considered. It is shown that solenoids with a magnetic field exceeding $B = 15$ T are required for focusing ion beams with a small charge-to-mass ratio $Z/A\approx 1/66$ in a superconducting accelerator.
