Abstract:
An apparatus for the creation of high current ion beams is disclosed. The apparatus includes an ion source, such as a RF ion source or an indirectly heated cathode (IHC) ion source, having an extraction aperture. Disposed proximate the extraction aperture is a bias electrode, which has a hollow center portion that is aligned with the extraction aperture. A magnetic field is created along the perimeter of the hollow center portion, which serves to contain electrons within a confinement region. Electrons in the confinement region energetically collide with neutral particles, increasing the number of ions that are created near the extraction aperture. The magnetic field may be created using two magnets that are embedded in the bias electrode. Alternatively, a single magnet or magnetic coils may be used to create this magnetic field.

Claim (Index 11):
An apparatus for creating a high current ion beam, comprising:\n an ion source for generating positive ions, comprising a plurality of chamber walls defining an ion source chamber, having a first chamber wall and a second chamber wall, opposite the first chamber wall, that includes an extraction aperture, wherein a plasma is created within the ion source chamber; a bias electrode disposed within the ion source chamber between the first chamber wall and the second chamber wall and proximate the extraction aperture, the bias electrode having an inner surface defining a perimeter of a hollow center portion that is aligned with the extraction aperture, and an outer surface opposite the inner surface; and a magnet disposed proximate the outer surface of the bias electrode and oriented with a first pole of the magnet disposed toward the first chamber wall of the ion source chamber and a second pole of the magnet disposed toward the second chamber wall containing the extraction aperture; wherein a magnetic field is created between the first pole of the magnet and the second pole of the magnet that encircles the bias electrode, and wherein a confinement region to contain electrons is created along the inner surface of the bias electrode by the magnetic field, and wherein positive ions are created in the ion source chamber between the first wall and the bias electrode, wherein positive ions are created in the ion source chamber between the first wall and the bias electrode, and pass through the hollow center portion and the extraction aperture to exit the ion source chamber.
