Patent ID: 8153958

Claim:
An apparatus for producing a hyperthermal beam, comprising: a plasma discharge source configured to receive an elemental source, generate plasma based on the elemental source, and generate one or more neutral atoms of the elemental source; an emission system configured to emit a hyperthermal beam, comprising the one or more neutral atoms of the elemental source, from the plasma discharge source through an aperture of the plasma discharge source; a magnetic source configured to provide a magnetic field and to collimate the hyperthermal beam in a first direction and control a size of the hyperthermal beam; and a diagnostics chamber and a skimmer aligned with the aperture, wherein the skimmer is configured to focus the hyperthermal beam, wherein the diagnostics chamber comprises a speed selector configured to select a translational energy of the hyperthermal beam, wherein the speed selector comprises one or more rotatable discs configured to allow a portion of the hyperthermal beam to pass through the one or more rotatable discs based on a rotational speed of the one or more rotatable discs and a size of a slit on the one or more rotatable discs, wherein the portion of the hyperthermal beam has the selected translational energy, and wherein the one or more rotatable discs comprise tungsten.
