ABSTRACT:
A target for an image pick-up tube employs a layer of lead monoxide P b O which exhibits substantially intrinsic conductivity. The surface region of the P b O layer is formed with a high energy level density effective to trap beam electrons landing thereon, while remaining in the intrinsically conductive state, by bombardment of the target surface with inert gas ions. Such a surface region effectively precludes injection of electrons into the target interior, and gives rise to improved resolution and dark current characteristics.
