Abstract
HIGH YIELD SECONDARY-ELECTRON SURFACES HOLD PROMISE FOR IMPROVED ELECTRON-MULTIPLYING DEVICES SUCH AS PHOTOMULTIPLIERS AND MICROCHANNEL PLATES. ION IMPLANTATION AND ION BEAM MIXING OFFER A DIRECT MEANS OF ALLOYING LOW WORK-FUNCTION ELEMENTS INTO THE NEAR SURFACE REGION OF SUBSTRATES. PRELIMINARY WORK HAS SHOWN PROMISE, AND THIS PROJECT WILL TEST THE FEASIBILITY OF PRODUCING STABLE, LONG-LIVED, LOW WORK-FUNCTION SURFACES BY ION BEAM ENHANCED DEPOSITION AND ION BEAM MIXING OF SELECTED ELEMENTS (E.G., MG, CA, AND SR) INTO ELECTRON-EMITTING SURFACES.
