Electron Beams, Lenses, and Optics, Volume I deals with the physics of electron beams, lenses, and optics and covers topics ranging from the paraxial ray in symmetrical electric fields to the analytical determination of electrostatic fields. The general properties of electrostatic lenses and the electrostatic immersion lens are also considered. Each equation except one is derived from first principles. To emphasize the physics of the discussions, elementary mathematics is used as much as possible. Comprised of eight chapters, this volume begins with an introduction to the laws that govern electron beams and light rays, including Snell's law. Some fundamental limitations to the analogy between electron optics and light optics are evaluated, together with electron rays in plane symmetrical and in rotationally symmetrical fields. Subsequent chapters explore the general properties of electrostatic lenses and electrostatic immersion lenses; electrostatic unipotential lenses; and formation of optical images by rotationally symmetrical magnetic fields. The final chapter is devoted to the symmetrical magnetic lens and its magnetic scalar potential, paying particular attention to the flux density along the z axis and factors to consider in the design of the pole pieces. This book will be of interest to students, practitioners, and researchers in physics.

Volume one of Principles of Electron Optics: Basic Geometrical Optics, Second Edition, explores the geometrical optics needed to analyze an extremely wide range of instruments: cathode-ray tubes; the family of electron microscopes, including the fixed-beam and scanning transmission instruments, the scanning electron microscope and the emission microscope; electron spectrometers and mass spectrograph; image converters; electron interferometers and diffraction devices; electron welding machines; and electron-beam lithography devices. The book provides a self-contained, detailed, modern account of electron optics for anyone involved with particle beams of modest current density in the energy range up to a few mega-electronvolts. You will find all the basic equations with their derivations, recent ideas concerning aberration studies, extensive discussion of the numerical methods needed to calculate the properties of specific systems and guidance to the literature of all the topics covered. A continuation of these topics can be found in volume two, Principles of Electron Optics: Applied Geometrical Optics. The book is intended for postgraduate students and teachers in physics and electron optics, as well as researchers and scientists in academia and industry working in the field of electron optics, electron and ion microscopy and nanolithography. Offers a fully revised and expanded new edition based on the latest research developments in electron optics Written by the top experts in the field Covers every significant advance in electron optics since the subject originated Contains exceptionally complete and carefully selected references and notes Serves both as a reference and text

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.

The three volumes in the PRINCIPLES OF ELECTRON OPTICS Series constitute the first comprehensive treatment of electron optics in over forty years. While Volumes 1 and 2 are devoted to geometrical optics, Volume 3 is concerned with wave optics and effects due to wave length. Subjects covered include: Derivation of the laws of electron propagation from SchrUdinger's equation Image formation and the notion of resolution The interaction between specimens and electrons Image processing Electron holography and interference Coherence, brightness, and the spectral function Together, these works comprise a unique and informative treatment of the subject. Volume 3, like its predecessors, will provide readers with both a textbook and an invaluable reference source.

The field of electron and ion optics is based on the analogy between geometrical light optics and the motion of charged particles in electromagnetic fields. The spectacular development of the electron microscope clearly shows the possibilities of image formation by charged particles of wavelength much shorter than that of visible light. As new applications such as particle accelerators, cathode ray tubes, mass and energy spectrometers, microwave tubes, scanning-type analytical instruments, heavy beam technologies, etc. emerged, the scope of particle beam optics has been exten ded to the formation of fine probes. The goal is to concentrate as many particles as possible in as small a volume as possible. Fabrication of microcircuits is a good example of the growing importance of this field. The current trend is towards increased circuit complexity and pattern density. Because of the diffraction limitation of processes using optical photons and the technological difficulties connected with x-ray processes, charged particle beams are becoming popular. With them it is possible to write directly on a wafer under computer control, without using a mask. Focused ion beams offer especially great possibilities in the submicron region. Therefore, electron and ion beam technologies will most probably playa very important role in the next twenty years or so.
