SYSTEM, APPARATUS AND METHOD FOR DEFLECTING A PARTICLE BEAM
First Claim
1. An apparatus comprising:
- at least six electromagnetic portions disposed on a plane, each of said at least six electromagnetic portions being aligned with a radius emanating from an axis normal to said plane and being distanced from said axis to form a volume about said axis;
at least six coils being configured for generating a dipole magnetic field in said volume in response to electrical current patterns applied to physically opposing coils, said dipole magnetic field comprising vectors being generally equal in magnitude with a same direction of orientation on said plane traversing said axis, said orientation being rotatable about said axis in response to a change in said current patterns to deflect a particle beam entering said volume in a direction away from said axis, each of said at least six coils being disposed about a one of said at least six electromagnetic portions; and
a yoke structure being configured for returning a generated magnetic flux.

Abstract
A variety of systems, apparatus and methods for deflecting a particle beam are described. An apparatus comprises at least six electromagnetic portions disposed on a plane. Each of the at least six electromagnetic portions is aligned with a radius emanating from an axis normal to the plane and is distanced from the axis to form a volume about the axis. At least six coils are configured for affecting a dipole magnetic field in the volume in response to electrical currents applied to physically opposing coils where a particle beam entering the volume is deflected. Each of the at least six coils is disposed about a one of the at least six electromagnetic portions. A yoke structure is configured for returning a generated magnetic flux.
