Quasars: Beacons at the Beginning of Time symmetric lenses of light optics, the basic properties of which were introduced in Section 1-4-2. The existence of the electron optical index of refraction (Section 2-6) proves the possibility of producing electron and ion lenses on the basis of the close analogy between light optics and the motion

Stationary magnetic fields cannot accelerate charged particles; therefore in t he absence of electrostatic fields magnetic lenses leave their energy unaltered.

The reduction of aberrations is especially crucial for ion beams. They must be focused by electrostatic lenses to ensure that the refraction is independe

The main feature of this type of deflection is that the undeflected beam has a ., therefore the analysis of deflection can be based on the principles used in the previous chapte
