  • Sputter ion pump with enhanced anode
    Patent number: 8439649
    Abstract: A sputter ion pump including an evacuateable envelope having a chamber, first and second cathodes and an anode disposed in the chamber. The anode can have an outer layer of a non-evaporable getter (NEG) material so as to permit NEG pumping of gases by the anode. In another aspect of the invention, the anode can be formed with spaced-apart first and second sheet portions disposed in juxtaposition to each other and having a plurality of holes extending through the sheets for forming a plurality of anode cells.
    Type: Grant
