A system for focusing and accelerating a beam of electrically charged particles, for example protons. The system comprises: a beam generator; a charge pulse generator; and a focusing and accelerating device comprising a body with a core. The body defines a charge path extending along the body and beam generator directs a beam of electrically charged particles through the core. The charge pulse generator simultaneously delivers charge pulses to the charge path. The charge path may be helical in shape. Movement of the charge pulse along the path creates an electric field that simultaneously accelerates and focuses the beam. |
