Application ID: 829
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.
This model example illustrates applications of this type that would nominally be built using the following products:COMSOL Multiphysics®
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
