Optics of Charged Particles describes how charged particles move in the main and fringing fields of magnetic or electrostatic dipoles, quadrupoles, and hexapoles using the same type of formulation and consistent nomenclature throughout. This book not only describes the particle trajectories and beam shapes, but also provides guidelines for designing particle optical instruments. The topics discussed include Gaussian optics and transfer matrices, general relations for the motion of charged particles in electromagnetic fields, and quadrupole lenses. The sector field lenses, charged particle beams and phase space, and particle beams in periodic structures are also elaborated. This text likewise considers the fringing fields, image aberrations, and design of particle spectrometers and beam guide lines. This publication is suitable for undergraduate students in physics and mathematics.

Optics of Charged Particles, Second Edition describes how charged particles move in the main and fringing fields of magnetic or electrostatic dipoles, quadrupoles, and hexapoles. Since the first edition published over 30 years ago, developments have progressed with a whole host of key technologies based on the foundational principles of charged particle optics. Fully updated and revised, this new edition gives special emphasis to information needed for the design of mass spectrometers and mass spectrographs, which are key tools in multiple areas, from organic chemistry and drug development, to environmental trace investigations and understanding the formation of elements. This book not only describes the fundamental particle trajectories and beam shapes involved, but also provides guidelines for designing particle optical instruments. For experienced researchers in the field it highlights the latest developments and guides them in applying charged particle optics to the design of new mass analysing instruments, whilst for those who may only need a foundational overview, it provides the background knowledge required to accurately understand and analyse results when using such tools. By providing a comprehensive overview of the field of charged particle optics, this Second Edition of Optics of Charged Particles supports all those working, directly or indirectly, with charged-particle research or ion- and electron-analyzing instruments, from either a design or application perspective. Provides enhanced, clear descriptions and derivations making complex aspects of charged particle behaviour and assessment easier to understand Assists the reader in applying insights obtained from charged particle optics to the design of new mass analysing instruments Discusses emerging applications and issues which have arisen since the first edition

This second edition is an extended version of the first edition of Geometrical Charged-Particle Optics. The updated reference monograph is intended as a guide for researchers and graduate students who are seeking a comprehensive treatment of the design of instruments and beam-guiding systems of charged particles and their propagation in electromagnetic fields. Wave aspects are included in this edition for explaining electron holography, the Aharanov-Bohm effect and the resolution of electron microscopes limited by diffraction. Several methods for calculating the electromagnetic field are presented and procedures are outlined for calculating the properties of systems with arbitrarily curved axis. Detailed methods are presented for designing and optimizing special components such as aberration correctors, spectrometers, energy filters monochromators, ion traps, electron mirrors and cathode lenses. In particular, the optics of rotationally symmetric lenses, quadrupoles, and systems composed of these elements are discussed extensively. Beam properties such as emittance, brightness, transmissivity and the formation of caustics are outlined. Relativistic motion and spin precession of the electron are treated in a covariant way by introducing the Lorentz-invariant universal time and by extending Hamilton’s principle from three to four spatial dimensions where the laboratory time is considered as the fourth pseudo-spatial coordinate. Using this procedure and introducing the self action of the electron, its accompanying electromagnetic field and its radiation field are calculated for arbitrary motion. In addition, the Stern-Gerlach effect is revisited for atomic and free electrons.
