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 THE PROPOSED EFFORTS WILL TEST THE FEASIBILITY OF PRODUCING STABLE LONG-LIVED WORK FUNCTION SURFACES BY DIRECT ION IMPLANTATION AND ION BEAM MIXING OF SELECTED ELEMENTS (E.G.,BA AND CS) INTO ELECTRON EMITTING SURFACES.
