Available in PDF, EPUB and Kindle. Book excerpt: Electrostatic Lens Systems: Second Edition enables readers to design lens systems for focusing beams of charged particles that have useful characteristics. The book covers the basic theory of the motion of charged particles in electrostatic fields and describes several methods for the calculation of the potential and field distribution for various electrode geometries. It emphasizes the Bessel function expansion method, developed by the author and his students, and the nine-point implementation of the finite difference method. Demonstration programs of other methods can be found via the websites provided. A chapter on aberrations presents formulae that enable the coefficients to be determined by an extension to the ray tracing procedures, demonstrating optimum conditions for lens operation. The book is accompanied by a disk that provides a suite of computer programs (LENSYS for MS-DOS) intended for practical use in the design and analysis of systems using round lenses with apertures or cylindrical elements. These programs are of value even to experienced workers in the field who may be quite familiar with much of the material in the text.

Book excerpt: The use of electrostatic lenses for the control of ion and electron beams has grown considerably in recent years. In addition, innovations in the production of low energy positrons have opened a whole new field of research for which electrostatic lenses are required. Electrostatic Lens Systems is therefore a timely treatise on the practical aspects of lens system design. The text gives a clear and concise treatment of the motion of charged particles in electrostatic fields and describes several methods of calculating the potential and field distributions for various electrode geometries. Electrostatic Lens Systems is also intended to be an interactive tutor on the practical design and analysis of systems using round lenses (both apertures and cylinders) through a unique suite of programs (provided on IBM compatible disc). Combined with an emphasis on the Bessel function expansion method and a thorough description of the well known relaxation methods, this volume will be a significant reference work and learning tool for experienced workers and new researchers alike. If you need to use electrostatic lenses then you need to read Electrostatic Lens Systems.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Focusing of Charged Particles, Volume II presents the aspects of particle optics, including the electron, the ion optical domains, and the accelerator field. This book provides a detailed analysis of the principles of the laws of propagation of beams. Comprised of three parts encompassing three chapters, this volume starts with an overview of how a beam of charged particles traverses a region that is at a uniform, constant, electrostatic potential. This book then discusses the principle of charge repulsion effect by which the space charge of the beam modifies the potential in the region that it traverses. Other chapters examine the general design techniques and performances obtainable for electron guns applicable for use in initiating a beam for linear beam tubes that is given in a condensed form. The last chapter deals with the two stable charged particles that can be accelerated, namely, protons and electrons. This book is a valuable resource to physicists, accelerator experts, and experimenters in search of interactions in the detector target.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
