Just like optical lenses focus light, electric and magnetic lenses can be used for focusing beams of charged particles.
This COMSOL Multiphysics model shows the path of B5+ ions passing through a focusing system of three magnetic quadrupoles. Each of the quadropoles focus the beam of ions in one transverse direction and defocus it in the other. The net effect on the beam after traveling through the system is focusing in all directions. Particle tracing of the ions is used to investigate the focusing effect of the quadropole.
