Abstract: An ion source has an arc chamber defining an arc chamber volume. A reservoir is coupled to the arc chamber, defining a reservoir volume. The reservoir receives a source species to define a liquid within the reservoir volume. A conduit fluidly couples the reservoir volume to the arc chamber volume. First and second openings of the conduit are open to the respective reservoir and arc chamber volume. A heat source selectively heats the reservoir to melt the source species at a predetermined temperature. A liquid control apparatus controls a first volume of the liquid within the reservoir volume to define a predetermined supply of the liquid to the arc chamber volume. The liquid control apparatus is a pressurized gas source fluidly coupled to the reservoir to supply a gas to the reservoir and provide a predetermined amount of liquid to the arc chamber.

Abstract: An electrode system for an ion source has a source electrode that defines a source aperture in an ion source chamber, and is coupled to a source power supply. A first ground electrode defines a first ground aperture that is electrically coupled to an electrical ground potential and extracts ions from the ion source. A suppression electrode is positioned downstream of the first ground electrode and defines a suppression aperture that is electrically coupled to a suppression power supply. A second ground electrode is positioned downstream of the suppression electrode and defines a second ground aperture. The first and second ground electrodes are fixedly coupled to one another and are electrically coupled to the electrical ground potential.

Abstract: A modular ion source and extraction apparatus comprises an ion source chamber selectively electrically coupled to a voltage potential, wherein the ion source chamber comprises an extraction aperture. An extraction electrode is positioned proximate to the extraction aperture of the ion source chamber, wherein the extraction electrode is electrically grounded and configured to extract ions from the ion source chamber. One or more linkages operably couple to the ion source chamber, and one or more insulators couple the extraction electrode to the respective one or more linkages, wherein the one or more insulators electrically insulate the respective one or more linkages from the extraction electrode, therein electrically insulating the extraction electrode from the ion source chamber. One or more actuators operably couple the one or more linkages to the ion source chamber, wherein the one or more actuators are configured to translate the one or more linkages with respect to the ion source chamber, therein translating the extraction electrode in one or more axes.
