In proximity focused electrostatic image tube; spatial resolution is a strong function of the cathode flatness.Topographic irregularities of the cathode surface establish transverse electric fields near the cathode.The fields impart a component of transverse momentum to the emitted electron, which, in turn,degrades the spatial resolution characteristic of… CONTINUE READING
