Despite the fact that we can consider the electron as a . particle, it has an angular momentum associated with a magnetic moment . Here, . ≈ 1. 6 10.

definite integrand of the integrals of the coefficients of spherical and chromatic aberration does not suffice to draw conclusions about the performance of round lenses. Although we cannot nullify the aberration coefficients, it may be possible to minimize the aberrations by skillful design to such

erested in the behavior of the charged-particle beam, which represents an ensemble of trajectories. In most cases, one characterizes the beam by its current and mean energy .. However, these quantities do not suffice to describe its focusing properties, which strongly depend on the emission characte
