Apparatus for producing a high energy beam of selected metallic ions
Abstract
Abstract A technique for producing a high energy beam of ions of a selected metal without having the selected metal initially in gaseous form and the application of the technique to treating solid bodies of material. An inert gas is ionized in the source chamber section of an accelerator. The exit channel section of the accelerator is made from a material which includes the preselected metal. A deflecting magnet is positioned along the path of the ion beam emerging from the accelerator. Included in the emerging beam are ions of the inert gas and ions of the preselected metal used in the exit channel. All ions except either those of the inert gas or those of the preselected metal are selectively discarded by regulating the current of the deflecting magnet. The undiscarded ions remaining in the beam are used to treat the solid body of material.
