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. Bias voltages are applied to at least one of the cathode, repeller and the electrodes, relative to the electrically conductive wall of the chamber. Further, the IHC ion source comprises a configuration circuit, which receives the various voltages as input voltages, and provides selected output voltages to the cathode, repeller and electrodes, based on user input. In this way, the IHC ion source can be readily reconfigured for different applications without rewiring the power supplies, as is currently done. This configuration circuit may be utilized with other types of ion sources as well.
