## Electrostatic Lens Systems,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. |
