Abstract: An ion source with an insertable target holder for holding a solid dopant material is disclosed. The insertable target holder includes a hollow interior into which the solid dopant material is disposed. The target holder has a porous surface at a first end, through which vapors from the solid dopant material may enter the arc chamber. The porous surface inhibits the passage of liquid or molten dopant material into the arc chamber. The target holder is also constructed such that it may be refilled with dopant material when the dopant material within the hollow interior has been consumed. The porous surface may be a portion of a perforated crucible, a portion of a perforated retention cap, or a porous insert.

Abstract: An IHC ion source with multiple configurations is disclosed. For example, an IHC ion source comprises a chamber, having at least one electrically conductive wall, and a cathode and a repeller disposed on opposite ends of the chamber. Electrodes are disposed on one or more walls of the ion source.
