  • Electron beam driven negative ion source
    Patent number: 5391962
    Abstract: A negative ion source is disclosed wherein an electron beam produced in one chamber is used to sustain a discharge in another chamber whose conditions are independently adjusted for optimum production of vibrationally excited hydrogen molecules. By including a provision for an independently controlled source of low energy electrons in a region near the extraction aperture, the optimum conditions for creation of H.sup.- ions by dissociative attachment are produced. In this manner the current and brightness of a H.sup.- beam may be maximized.
