Use of Matrices to Represent Electron Lenses. Matrices for the Two-Tube Electrostatic Lens
D DiChio, S Natali, C Kuyatt, A Galejs
The use of matrices to represent electron lenses is discussed. It is shown that it is more convenient and natural to represent a lens by a matrix and that the matrix elements show a more regular behavior than do the focal properties. Thus matrices are more convenient to use in computer programs. Matrix elements for the two-tube electrostatic lens are presented and their properties discussed. A simple analytical form for the matrix elements of lenses with near-unity voltage ratios is given.
