International Technical Digest on Electron Devices Meeting, 2003
The secondary electron emission of pure metals, cathodes and insulators was measured. The secondary electron emission yield was measured at room temperature and at temperatures up to 1100 degrees C. The cathodes were life-tested at 850 degrees C and were measured at regular intervals at room temperature during a period of 10000 h.

Surface Review and Letters, 1997
Basic aspects of energetic electron–atom scattering suffered by incident (primary) and/or excident (Auger, backscattered) electrons during propagation in (at least locally) ordered solids are reviewed. Scattering interference results in the dependence of total or partial electron yield on the incidence and/or takeoff angle.

Simulation of convoy-electron emission
Physical Review A, 1992We present a microscopic simulation of convoy-electron production and transport through solids. Using a classical transport theory, we calculate the forward-ejected electron spectrum for 3-MeV/u H{sup 0} projectiles traversing carbon foils of different thicknesses.

Prebreakdown Electron Emission
IEEE Transactions on Electrical Insulation, 1983Recent evidence suggests that the prebreakdown currents that flow between vacuum-insulated high voltage electrodes frequently originate from a non-metallic emission mechanism which is thought to be assocaited with some form of insulating/ semiconducting surface oxide or impurity concentration.

Cluster induced secondary electron emission
International Journal of Mass Spectrometry and Ion Physics, 1976Abstract By means of a new ion-electron converter having a spherically shaped stainless-steel conversion electrode, the electron yields of various atomic ions, molecular ions and cluster ions were investigated for a fixed ion energy of 15 keV. The pulse height distributions obtained can be approximately described by Poisson distributions for atomic ...

Electron emission microscope for use in electron emission sites observations
Applied Surface Science, 1999An electron emission microscope (EEM) constructed for electron emission sites observations is presented. This EEM consists of three unipotential lenses, a microchannel plate, and a phosphor screen, and has the advantage that it enables the observation of electron emission sites of not only a sharp point cathode, such as a field emitter, but also a ...

When the surface of a solid is bombarded with charged particles of sufficient kinetic energy, emission of electrons by the solid may be observed. This phenomenon of secondary electron emission was discovered by Austin and Starke in 1902 in a study of the reflection of electrons by metals; they observed that under certain circumstances more electrons ...

Monochromators require feed beams with defined aperture angles and a low energy spread. After presenting some basic concepts of thermionic emission we describe the technical aspects of trajectory calculations in the presence of space charge. Emission systems with differently shaped lenses are studied and their performances are compared.
