Embodiments of the invention relate to a mass resolving aperture that may be used in an ion implantation system that selectively exclude ion species based on charge to mass ratio (and/or mass to charge ratio) that are not desired for implantation, in an ion beam assembly. Embodiments of the invention relate to a mass resolving aperture that is segmented, adjustable, and/or presents a curved surface to the oncoming ion species that will strike the aperture. Embodiments of the invention also relate to the filtering of a flow of charged particles through a closed plasma channel (CPC) superconductor, or boson energy transmission system.
