Abstract
An ion source that includes a material delivery system to deliver a metal dopant in the form of a wire to the ion source is disclosed. The wire is introduced through an opening in one wall of the arc chamber and is sputtered or chemically etched by the plasma. The rate at which the wire is delivered may be controlled so as to maintain a desired beam current without causing any liquid metal to be spilled in the arc chamber. In some embodiments, the wire may be heated or cooled prior to entering the ion source. In some embodiments, a dopant power supply may be employed to supply a bias voltage to the wire. A controller may be used to control various parameters associated with the metal dopant, including delivery rate, dopant voltage and dopant temperature.
