A duoplasmatron is provided having a cathode, an anode with linear slit, and an intermediate electrode (IE) between the cathode and the anode where the IE has an opening that is aligned with the anode slit. A magnet forms a magnetic field that passes through the anode slit. A discharge passes from the cathode to the anode through the IE opening and the anode slit. The discharge is constricted through the IE opening and the magnetic field in the anode slit. An extractor external to the anode accelerates ions through an ion emitting slit aligned with the anode slit. A process of generating an accelerated ion beam is provided that includes flowing a gas into the IE and then energizing at least one power supply to induce electron flow to the anode. Ionizing the gas in the gap between the IE and anode. The ions are accelerated from the anode through the extractor ion emitting slit forming a linear ion beam. |
