A common way to focus a beam of charged particles is to use an electric field and a magnetic field together. Based on the relative strength and orientation of the two fields, you can tune the Coulomb and Lorentz forces to direct the beam of particles. This technique is common in mass spectrometers and scanning electron microscopes. You want to focus a beam of positively charged particles moving in the -z direction.
