We have discussed the role of the beam’s own space charge as a source of aberrations in Section 5-6-2. We know that space charge has two basic forms: distributed charge and interactions of individual particles. In this chapter the problem of distributed space charge will be considered in some detail, followed by a short discussion of the Boersch effect.
