پرتوهای الکترونی، لنزها و اپتیک: جلد دوم

Electron Beams, Lenses, and Optics, Volume 2 deals with the aberrations relating to electronic optics. This book discusses the geometrical aberrations of lenses; spherical aberration of electric and magnetic lenses; and measurement of the spherical aberration of various electric and magnetic lenses. The theory of diffraction; influence of space charge in high density electron beams; and chromatic aberration are also deliberated. This publication likewise covers the classification of the geometrical aberrations; derivation of the coefficient of spherical aberration according to Glaser; and pepper-pot method or Hartmann's test. The Fraunhofers diffraction through a circular aperture; force due to coulomb repulsion; and upper limit of the chromatic aberration of magnetic lenses are also included. This volume is valuable to industrial scientists and engineers concerned with electrostatic and magnetic lenses.
