Electron yield of glow discharge cathode materials under helium ion bombardment

Electron Emission from Inconel under Ion Bombardment

Electron yields from clean and oxydized Inconel 625 surfaces have been measured for H', H:, Hef, 0' and Ar+ ions at normal incidence in the energy range 1.5-40 keV. These measurements have been made under ultrahigh vacuum and the samples were freed of surface contaminants by bombarding with high doses of either 20 keV H l or 30 keV Ar+ ions. Differences in yields of oxydized versus clean surfac...

A Self-Consistent Model for Negative Glow Discharge Lasers: The Hollow Cathode Helium Mercury Laser

A model for negative glow metal-vapor ion lasers that self-consistently describes the dynamics of the negative glow and the cathode sheath regions of the discharge has been developed. The model computes the electron energy distribution and the population of relevant excited states in the negative glow self-consistently with the charged particle fluxes and electric field distribution in the cath...

Study on the Ionic Bombardment in a Glow Discharge Lamp

The surface of copper alloys was studied by means of a scanning electron microscope after having been sputtered by a glow discharge source under typical conditions for spectrochemical analysis. The surface topography developed during the process of sputtering gave the following two results: It would appear that the energy spread of the bombarding ions is small and the variation in the angles of...
