Publisher's Synopsis
This book provides a very basic introduction to electron optics: the underlying physics of the behaviour of charged- particle beams in electromagnetic fields. Whereas other texts attempt to cover many different applications or to give the newest and latest developments at an advanced level, "Basics of;Electron Optics" guides the reader thoroughly through what he or she needs to know to be able to use and handle design and construction of electron-optics devices efficiently.;The author covers trajectory equations, electromagnetic fields,;Coulomb (space-charge) forces between charged particles, basics of analytical and numerical analyses and phase-space methods.;Also included are several novel analyses of circularly symmetric and planar electron lenses, a numerical treatment of space charge in long pencil beams and an analytical treatment in cylindrically symmetric diode regions with radially-varying emission currents.
