In this paper, we investigate the oxide cathodes for the development of reliable electron sources. Poisoning in oxide cathodes is one of the serious problems in achieving reliable electron emission. In particular, early poisoning induces poor life pe

The objective was to prepare scandium oxide layers on tungsten for the surface study of Sc-O/W(100) emitters using two design types of a compact evaporator for Sc 2 O 3 and for metallic scandium deposition. Both of these evaporators were compatible w

— Simulation of a CRT with a flat outer surface and a spherical inner surface was performed to determine the virtual screen image made by refraction in the glass panel. The simulation calculated the radius of the panel inner surface for the flat-fa

The greater part of the beam current in current color CRTs is blocked by the aperture masks. Consequently relatively high electron beam currents are required to obtain sufficient brightness, and this usually leads to increased beam spot size on the p

The luminescence from a cyclohexane solution containing p-terphenyl irradiated with 60Co γ-rays has been quenched by various compounds. The quenching efficiencies were found to be in the following order; sulfur hexafluoride∼carbon tetrachloride>ni
