The ability to correct the effects of spherical aberration in electron lenses, whether by software reconstruction or hardware correctors, allows direct interpretation of TEM images down to the information limit of the system.
A great advantage of the transmission electron microscope is in the capability to observe, by adjusting the electron lenses, both electron microscope images (information in real space) and diffraction patterns (information in reciprocal space) for the same region.
The book consists of two parts: Part I focuses on the motion of charged particles in static fields, the theory of electron lenses, and the problems of formation and transport of intense electron beams are considered; Part II covers the principles and theory of the interaction of electron beams with electromagnetic waves in quasi-stationary systems (diodes, klystrons), systems with continuous interactions (traveling wave tubes and backward wave oscillators), crossed-field systems (traveling wave and backward wave tubes of M-type, magnetrons, crossed-field amplifiers.
