Solid He-4 targets were prepared by implantation of He ions of various energies into thin Al foils. The targets were tested using the proton Rutherford backscattering (RBS) technique. The rests showed that a considerable amount of the implanted He atoms stays in the host foils for a long time after the implantation. A possibility of using the He-implanted targets in experiments with radioactive beams is demonstrated. Further steps to increase He amount in the implanted targets are discussed.
