THE ELECTRON-OPTICAL PROPERTIES OF AN IMAGE CONVERTER,

Abstract

The field distribution and electron-optical properties of an electrostatically-focused image converter with a plane cathode are determined precisely by means of a resistance network analogue and numerical computation. The axial potential distribution can be expressed by the empirical formula phi = A sinh kz. Graphs are given, showing the dependence of coefficients A, k, the position of gauss-image plane, and the linear magnification on inter-electrode spacing. An approximate formula for calculating the distortion-coefficient is derived, which agrees fairly well with experimental result. Design factors are discussed. (Author)
