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 17):
A method of creating a high current ion beam, comprising:\n generating a plasma comprises positive ions within an ion source chamber, the ion source chamber having an extraction aperture; disposing a bias electrode having a hollow center portion proximate the extraction aperture; creating a magnetic field around at least a portion of a perimeter of the hollow center portion to form a confinement region; and extracting the positive ions from the ion source chamber through the hollow center portion and the extraction aperture; wherein electrons confined in the confinement region collide with neutral particles to create a high density localized plasma near the extraction aperture.
