Claim 13:
14. The IBE system of claim 13,
wherein the screen grid is configured to receive a screen grid voltage to extract the ions from the plasma within the plasma chamber to form the ion beam through the hole;
wherein the extraction grid is configured to receive an extraction grid voltage and wherein an ion current density of the ion beam through the hole depends on a voltage difference between the screen grid voltage and the extraction grid voltage;
wherein the accelerator grid is configured to receive an accelerator grid voltage and wherein an ion beam energy for the ion beam through the hole depends on a voltage difference between the extraction grid voltage and the accelerator grid voltage; and
wherein the decelerator grid is configured to receive a decelerator grid voltage.
