PhD thesis, Electrical Engineering.
The interaction of plasma with polymeric substrates generates both roughness and charging on the surface of the substrates. This work, toward the comprehension and, finally, the control of plasma-induced surface roughness, delves into the intertwined effects of surface charging, ion reflection, and secondary electron-electron emission (SEEE) on roughness evolution during Cited by: 5.

Chapter 21 Materials Source Investigation and Report Overview A geotechnical site investigation of WSDOT-owned or -leased materials sources is required in order to determine the quality and quantity of materials available for WSDOT construction projects. These materials include gravel base, crushed. Optical emission spectroscopy using arc and spark excitation (Arc Spark OES) is the preferred method for trace metal analysis to determine the chemical composition of metallic samples. This process is widely used in the metal making industries, including primary producers, foundries, die casters and manufacturing.

The purpose of this article is to investigate experimentally argon ion sputtering on secondary electron emission of Au.
Argon ion sputtering is used to remove contaminations. The surface composition is monitored by X-ray photoelectron spectroscopy (XPS) and the surface topography is scanned by scanning electron microscope (SEM) and atomic force Cited by: We investigate the mechanism of the nonlinear secondary ion yield enhancement using Au n + (n=1, 2, 3, 5, 7) primary ions bombarding thin films of IrganoxDL-phenylalanine and polystyrene on Si, Al, and Ag substrates.
The largest differences in secondary ion yields are found using Au+, Au 2 +, and Au 3 + primary ion beams.
A smaller increase in Cited by: Secondary ion mass spectrometry (SIMS) is widely used to study the chemical composition of surfaces in areas from biological systems to materials chemistry [1, 2].One of the problems with the SIMS analysis of surfaces is that low secondary molecular ion yields are often observed for atomic primary ion by: Abstract.

The evolution of a RuO 2 –TiO 2 film electrode has been studied as a function of temperature by secondary ion mass spectrometry (SIMS). The coating mixture prepared on a titanium support from an isopropyl alcohol solution of hydrated ruthenium chloride and titanium diisopropoxide bispentane-2,4-dionate precursors was heated to various temperatures and analysed by SIMS.
This book emerged from a discussion meeting held at the Royal Danish Academy of Sci-ences and Letters in May It covers a broad scope of applications and fundamentals in the area of ion beam science. Applicationsin astrophysics,magneticand inertial fusion, particle therapy and radiation biology are followed up by topics in materials.

Wu, D.R. Swenson1, P. Kneisel, G. Wu2, Z. Insepov3, J. Saunders, R. Manus, B. A mass spectrometer ion collector system has been devised for the investigation of secondary electron emission by impact of ions on surfaces.
Results are reported for various ions incident on clean, baked (but not atomically clean) surfaces of AgMg, CuBe, and Nichrome V targets. For rare gas isotopic ions it is found that for a given energy ion the value of γ varies Cited by: Multipactor induced by secondary electron emission (SEE) is a potential risk for many high-power systems.
It is of great importance to suppress the total electron emission yield (TEEY) to mitigate the detrimental effect. This effect provides mostly emission of secondary electrons that can be used for depositing materials onto a substrate through gas assisted deposition, which involves exposing the sample to molecules in the gas phase whilst targeting the surface with the ion beam.
These materials can include metals such as platinum and tungsten, and also. In this investigation, you will explore some of your students' ideas about what things are made of and how different materials behave. You will help them distinguish between “objects” and "materials," and you will help them identify different kinds of .Electrodynamic tethers (EDTs) are long conducting wires, such as one deployed from a tether satellite, which can operate on electromagnetic principles as generators, by converting their kinetic energy to electrical energy, or as motors, converting electrical energy to kinetic energy.
