Focusing Ions with a Quadrupole Lens
Model ID: 1416
Just like optical lenses focus light, electric and magnetic lenses can focus beams of charged particles. Systems of magnetic quadrupole lenses find a common use in focusing both ion and particle beams in accelerators at nuclear and particle physics centers.
This model shows the path of ions going through three consecutive magnetic quadrupole lenses.
The model also takes fringing fields into account, and the calculation of the forces on the ions uses all components of their velocities.
