Zusammenfassung: | A permanent-magnet particle beam apparatus and method incorporating a non-magnetic portion for tunability are provided. The permanent-magnet particle beam apparatus includes a particle beam emitter that emits a charged particle beam, and includes a set of permanent magnets forming a magnetic field for controlling condensing of the charged particle beam. The permanent-magnet particle beam apparatus further includes a non-magnetic electrical conductor component situated with the set of permanent magnets to control a kinetic energy of the charged particle beam moving through the magnetic field. |
