Parallel Plasma Field Directed Sputter Sharpening of Field Emitters
… emitters using a DC glow discharge plasma as the ion source in conjunction with field directed sputter sharpening methodology. With field directed sputter sharpening, a positive voltage bias is applied to the field emitter and impinging ions are repelled away from the apex of the tip to the shank …

Quantifying the adhesion of noble metal foulants on structural materials in a Molten Salt Reactor
… Reactor (MSR) Experiment (MSRE), selected fission products deposited on the wetted surfaces throughout the reactor. Fission products such as molybdenum and ruthenium are noble with respect to the electrochemical potential of the fluoride fuel salt and therefore remain insoluble in their …

Experimental and Modeling Studies of Low-Energy Ion Sputtering for Ion Thrusters
… xenon-molybdenum (Xe+-Mo) sputtering yields for ion energies of 100 eV and less. Sputtering yield data at these energies are important for ion thruster design and lifetime prediction. The basic principles of sputtering phenomena are discussed. An overview of various popular types of experimental …

LEEDS studies of adsorbate-induced reconstruction of metal surfaces
… the technique of low-energy electron diffraction (LEED), the structures of three systems have been investigated, where small, electronegative atoms chemisorb and induce reconstruction at a metal surface; these surfaces are designated Ni(111)-(2x2)-0,Cu(110)-(2x3)-N, and Pd(100)-(V5x45)R27°-0. …
