Analyze charged particle trajectories with this tool. Ion Lenses help you calculate the trajectories of charged particles (ions and electrons) in an electrostatic field that acts as an electrostatic lens.
It enables you to adjust the potentials of 6 point charges, as well as their positions. In addition, the point charges can be moved by dragging them with the mouse, and the incident angle of the ion beam as well as its width can be controlled by the user.
