Optics of Charged Particles, 2nd edition, describes how charged particles move in the fields of magnetic and electrostatic dipoles, quadrupoles, higher order multipoles, and field-free regions. Since the first edition, published over 30 years ago, new technologies have emerged and have been used for new ion optical instruments like, for instance, time-of-flight mass analyzers, which are described now. Fully updated and revised, this new edition provides ways to design mass separators, spectrographs, and spectrometers, which are the key tools in organic chemistry and for drug developments, in environmental trace analyses and for investigations in nuclear physics like the search for super heavy elements as well as molecules in space science. The book discusses individual particle trajectories as well as particle beams in space and in phase-space, and it provides guidelines for the design of particle optical instruments. For experienced researchers, working in the field, it highlights the latest developments in new ion optical instruments and provides guidelines and examples for the design of new instruments for the transport of beams of charged particles and the mass/charge or energy/charge analyses of ions. Furthermore, it provides background knowledge required to accurately understand and analyze results, when developing ion-optical instruments. By providing a comprehensive overview of the field of charged particle optics, this edition of the book supports all those working, directly or indirectly, with charged-particle research or the development of ion- and electron-analyzing instruments.

Key Features

  • Provides enhanced, clear descriptions, and derivations making complex aspects of the general motion of charged particles understandable as well as features of charged particle analyzing instruments
  • Assists the reader in applying insights obtained from the principles of charged particle optics to the design of new transporting and mass- or energy-analyzing instruments for ions
  • Discusses new applications and newly occurring issues, which have arisen since the first edition


Anyone who needs an understanding of charged particle optics for their work, including physicists, chemists (particularly those in physical, theoretical and analytical chemistry), electronic device and materials developers needing an understanding or charged particle behaviour or using materials chemistry in their work, chemical engineers

About the Author

Hermann Wollnik

Prof. Hermann Wollnik’s work has taken him around the world and includes collaborations with the European Space Agency, the GSI research center in Darmstadt, Germany or with CERN in Geneva, Switzerland, with the Los Alamos and Oak Ridge National Laboratories in the United States as well as with the University of Osaka, Japan. After retiring from the Justus Liebig University in Giessen, Germany in 2001, he took up new collaborations with the New Mexico State University in Las Cruces, NM, United States and the GSFC of the NASA in Baltimore, MD, United States as well as with the KEK/RIKEN Research Institute in Tokyo, Japan. Prof. Wollnik’s main scientific work has concentrated on mass determinations and, thus, nuclear binding energies of isotopes of short-lived heavy and super heavy elements as well as on the identification of organic molecules on the earth and space objects as for instance on a comet head in the ROSETTA space mission. Among many different ideas were new proposals and designs of energy-isochronous time-of-flight mass spectrographs, for high- and low-energy ions, the developments of which he started in the mid-1970s.
