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.
