Surface Production of Negative Hydrogen Ions.
Abstract
Surface production of negative hydrogen ions by bombarding metal surfaces with cesium and hydrogen ions has been studied. Angular and energy distributions and the yield of the H(-) ions have been measured as function of energy and ion mix. Synergistic effects due to simultaneous hydrogen and cesium ion bombardment produce a higher H(-) yield than the sum of the individual processes. Cesium coverage on metal surfaces due to cesium ion bombardment has been studied . High coverages corresponding to a work function of 1.6 eV can be obtained at 100 eV energy when the target mass is smaller than the cesium mass. Keywords: Ion Emission; Atom; Molecule and Ion Impact; Sputtering; Ion Sources.
