Ion source with multiple configurations

An ion source, comprising:

• a chamber, comprising at least one electrically conductive wall;
• a configuration circuit in electrical communication with the electrically conductive wall;
• a plurality of power supplies, an output voltage of each of plurality of power supplies in communication with the configuration circuit;
• and
• at least one component, wherein the components comprise:
• a cathode disposed on one end of the chamber;
• a repeller disposed on an opposite end of the chamber;
• a first electrode disposed on one side wall;
• and
• a second electrode disposed on a second sidewall;
• wherein the configuration circuit selects an output voltage to be supplied to the at least one component, wherein each output voltage is selected from the output voltage of one of the plurality of power supplies or a voltage of the electrically conductive wall such that the configuration circuit allows the ion source to be operated in a plurality of modes.
