Quadrupole Lens

Application 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.

This application was built using the following:


The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
